So when Node.js returns a watcher object, it might be watching a path or an inode depending on the platform and file system. Of course if you often need both you can also create a hook that provides both out of the box, thus reproducing the previous behavior. Out of the box, moment.defaultFormat is the ISO8601 format YYYY-MM-DDTHH:mm:ssZ. ISO8601 string. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong. From version 2.11.0 months can also be an object, specifying standalone and format forms (nominative and accusative). It has many Several other libraries, especially date pickers and graphing libraries, take Moment as a dependency. In order: You may also specify a locale and strictness argument. From version 2.20.0, you may call .toISOString(true) to prevent UTC conversion. So Jan 15 to Feb 15 should be exactly 1 month. * As with the other getters for durations, moment.duration().weeks() gets the weeks (0 - 4). This is because passing an undefined value to an AND or NOT operator is the same The first argument will be parsed as a moment, if not already so. In Visual Studio Code, file names or globs can be added under "Auto Import File Exclude Patterns" in the Settings UI, or in a .vscode/settings.json file: This can be useful in cases where you cant avoid having certain modules or libraries in your compilation but you rarely want to import from them. If you are making a comparison in an if statement, use the logical AND (&&) operator to make sure the property is of the correct type. Operator in TypeScript August 6, 2020. Moment has evolved somewhat over the years, but it has essentially the same design as it did when it was created in 2011. is in actual DST or not. an actual time zone -- time in a particular location, like This is similar to moment.to, but is special-cased Durations do not have a defined beginning and end date. */, item: IData, e: React.MouseEvent, // Obj { name: any, age: any, number: any }, /** This is in contrast to the AND and NOT operators, which will both return all the users If you want an oriented duration in a month, a month ago (with suffix), A good reason to switch to contexts is if the state is accessed by a lot of components. All of the following produce invalid moments: The following produce a localized version of 'InvalidDate': And these return null or NaN with some structure: After a moment object is created, all of the inputs can be accessed with Creating a "Moment v3" that was immutable would be a tremendous undertaking and would make Moment a different library entirely. Please provide feedback, and consider contributing to this effort - especially if you have experience using Moment or other date and time libraries! Accepts numbers from 0 to 59. (i.e is the clock officially in DST at a given moment or not), so for things to ISO-8601 is a standard for time and duration display. As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. But thats not the case here. TypeScript now recognizes this, and allows assignments from unknown to {} | null | undefined. measurably after the one created in moment(), so the call would return If we do this naively, it means that every single component which uses that context will re-render every 15 seconds. operator in a similar way. false. TypeScript is currently in development for version 4.9. , removeChildasitem.firstChildChildNodeTSpaperitem.firstChildChildNode | nullTSpaper item.firstChildChildNode, HTMLInputvaluewidthplaceholdermax-lengthInput, , buttombuttonbutton&button , , Partial keyofinkeyof key , keyof , in , , Partial, keyof T T , in , P, T[P] ?, Required , -?Partial, TreadonlyReadonly, Readonly IPerson, Record KT, Exclude , Pick Exclude Pick Exclude Omit , typeof foo (type: any) => boolean, ReactAxiosAxios Promise HTTP node.js Axios , AxiosAxiosTypeScriptAxiosAxios All the shorthand keys from moment#add apply here as well. When you install it, it will wrap moment and you will be able to parse Hijri dates. For example, unknown is close in spirit to the union type {} | null | undefined because it accepts null, undefined, and any other type. To load a locale, pass the key and the string values to moment.locale. *, /** If the type of x were unknown we would have gotten this error instead: In addition, using any lets you cheat by performing operations that are not necessarily safe. When you use this approach, you basically tell TypeScript that this value will never be undefined or null . Create a clone of a duration. Note that adding an invalid duration to any other duration results in an invalid Any value can be assigned to a variable of type unknown. The default behavior of the module is to extract the JWT from the Authorization header as an OAuth2 Bearer token.. But we might use isarray without realizing that detail. In TypeScript 4.8, these binding patterns are never used as candidates for type arguments. string), NaN (not a number). In addition to assigning a global locale, you can assign a locale to a specific TypeScript is super set of JavaScript. It is based on and similar to the moment.twitter plugin but has a different output. For example, by default more than 45 seconds is considered a minute, more than 22 hours is considered a day and so on. You can get or set the locale of a duration using locale(). Because there is no specification on which formats should be supported, what works in some browsers will not work in other browsers. This can now better convey what a library will do at runtime, and give more precise types. But you can use type guards to narrow the type and get accurate type-checking for blocks of code operating on narrowed types. should return a formatting string. moment.duration().asHours() gets the length of the duration in hours. It's generally better to structure program logic so that TypeScript understands when values may be nullable. But It's important to know when to use useState and when to use useContext. * value around similar to how youd use instance fields in classes. never : T; // Used to fail because 'T' was not assignable to 'NonNullable'. If you want to format times in a short way, you can use the moment-shortformat plugin by @researchgate. Given any type of the form T extends U? For consistent results parsing anything other than ISO 8601 strings, you should use String + Format. To get the number of seconds in a duration, use moment.duration().seconds(). // assignable to parameter of type 'string'. You can read more in Luxon's documentation. String values (as shown on the last line) are supported from version Note: Support for the week and ordinal formats was added in version 2.3.0. If the range is exceeded, it will bubble up to the hour. 2.16.0 deprecated using moment().months(). Moment currently checks the winter and summer time, and if the offset matches If you are familiar with java.time, Joda-Time, or Noda Time, you will find js-Joda comparable. In particular, Node.js environments require internationalization support provided by ICU. If it's not equal to undefined, it gets assigned to the message variable, If the inclusivity parameter is used, both indicators must be passed. for the current time. For these, the lowercase tokens use the locale aware week start days, and the uppercase tokens use the ISO week date start days. You need not specify parsing flags recognized by Moment; the Moment will be invalid nonetheless, and the parsing flags will be returned by parsingFlags(). The supported measurements are years, months, weeks, days, hours, minutes, and seconds. So use unknown when a value might have any type, or when it is not convenient to use a more specific type. As of 2.11.0, duration format strings with a space between days and rest Once you load a locale, it becomes the active locale. for a list of valid (case-sensitive) arguments to this method. Note: before 2.3.0, Moment objects in this condition always returned false for moment#isValid; they now return true. by Date.prototype.getTimezoneOffset). undefineddata?.subjectId as number In some cases, TypeScript will pick up a type from a binding pattern to make better inferences. This is used in parsing the a A tokens. In contrast, moment.parseZone() parses the string but keeps the resulting Moment object in a fixed-offset timezone with the provided offset in the string. Durations are mutable, just like moment objects, You can find examples in moment/src/locale/fr.js and moment/src/test/locale/fr.js. Any value can be assigned to a variable of type unknown. */, /** // Note that `javascript.preferences.autoImportFileExcludePatterns` can be specified for JavaScript too. localized Invalid date string. the day of the month will change to the last day in the final month. You're now equipped to improve your usage of React Contexts. arbitrary so it was changed. However, Moment was built for the previous era of the JavaScript ecosystem. Like Locale#months, Locale#monthsShort can be a callback function as well. objects. If you pass true, you can get the value without the suffix. All the meetings and politics necessary to push proposals through happen completely externally to Github. */, /** It will return a number between 0 and 59. As demonstrated above, code like this has a potential bug the values null and undefined can be indirectly passed through these unconstrained type parameters to code that is not supposed to observe those values. Another change is that {} intersected with any other object type simplifies right down to that object type. union type The same keys and shorthands used to create durations can be used here as the second argument. moment.duration().asWeeks() gets the length of the duration in weeks. Mutates the original duration by subtracting time. If you are wanting to set the offset globally, // Destructors are only allowed to return void. The number argument refers to the number of units for that key. As of 2.21.0 when attempting to create a moment with the newly defined locale, moment will attempt to lazy load the parent if it exists. If you want to parse or display a moment in UTC, you can use moment.utc() instead of moment(). If it doesnt see that the string can be "round-tripped", then it will fall back to the base primitive type. This plugin extracts the format of a date/time string. The following parsing flags result in an invalid date: In addition to the above, As of 2.13.0 the meridiem and parsedDateParts flags work together to determine date validity. Moment will still create a moment global, which is useful to plugins and other third-party code. It's quite common for contexts to only be available in a section of the app, and in those cases it's quite easy to use a context where it's not available. Then the value would default to undefined without us knowing. */, /** Even then, not all modern implementations have implemented this specification correctly (e.g., Safari). You want useState to be your default option for state and only switch to useContext if it's necessary. If you want to limit the granularity to a unit other than milliseconds, pass the units as the third parameter. Consider objects like Nodes, Symbols, etc. If that fails, the code normally tries to chop the last bit (normally Locales: Custom data files that can be individually imported, Locales: Custom data files via add-on module, Time Zones: Custom data files via add-on module, Not every environment will implement the full specification. Many other optimizations where were able to reuse information across --build, --watch, and --incremental have been introduced as well. The first argument will be parsed as a moment, if not already so. For example, these conditional types extract the argument and return types from a function type: If T is a function type then the compiler infers its argument types or return type. Instead, we will be able to use capabilities of the JavaScript language itself. Use moment().month() instead. Be sure to specify the charset to prevent encoding issues. Optional chaining is issue #16 on our issue tracker. Type assertions are used when we have information about the type of a value that TypeScript can't know about. Note: moment#startOf('date') was added as an alias for day in 2.13.0. To run the tests in Node.js, do npm install, then grunt. So for example if the array has the sequence. Note: If you have trouble importing moment, For Typescript 2.x try adding "moduleResolution": "node" in compilerOptions in your tsconfig.json file, For Typescript 1.x try adding "allowSyntheticDefaultImports": true in compilerOptions in your tsconfig.json file and then use the syntax. Well, on a fairly large internal codebase, weve seen time reductions on the order of 10%-25% on many simple common operations, with around 40% time reductions in no-change scenarios. Nullish Coalescing: The ?? We use never in the else branch of each condition to make that case an error: // Error: Type '3' is not assignable to type 'never'. You can read up on the change here. time that are supported for moment#startOf are supported for If your locale uses 'am/pm', Locale#meridiem can be omitted, as those values are the defaults. Explore and manipulate data in your projects, Learn about applications built with Prisma, Up-level your applications with our Data Platform. It's a bit counter-intuitive if you ask me, but it's the way it works. They used to default to start-of-today before 2.14.0, but that was Use these methods to ensure compatibility. * After about a day of working on the problem and turning the program upside down, in a post someone had mentioned Lucid. It has been deprecated in favor of moment#add(Number, String). As discussed here, the duration format for Moment.js differs very slightly from the specifications for ISO 8601 nominal duration and RFC 5545 duration. Partial seconds are supported as well 23:59:59.999. If nothing is passed to moment#isAfter, it will default to the current time. If the string or format you are asking to change is reflected in the. It will be removed in next major release. Type aliases and interfaces are very similar, and in many cases you can choose between them freely. * Construct a type with a set of properties K of type T value is a string before passing it to the function. Wed like to extend our thanks to Marc Celani and his team at Airtable who invested lots of time in investigating the issues they were experiencing and pointing out the root cause. This is sometimes called timeago or relative time. Thank you to reddit user /u/tharrison4815 for pointing out some confusing wording in that section and helping me improve it. duration.humanize has thresholds which define when a unit is considered a minute, an hour and so on. See, Most newer environments provide IANA time zone support via the, Day of Week in three letters, followed by an optional comma. Check if a moment is before another moment. For more details, scroll to "Why date-fns?" not "correct" and won't work for all cases. By default, moment#diff will truncate the result to zero decimal places, returning an integer. * } You can eliminate the lowercase l tokens and they will be created automatically by replacing long tokens with the short token variants. As of version 2.20.0, the following HTML5 formats are available as constants in the moment object's HTML5_FMT property (moment.HTML5_FMT. , Event event anyTypeScriptevent, EventinterfaceReactEvent, EventElement, onChangeFormEventHTMLInputElementinput If we pass null,undefined,0,false,,NaN values to the if condition it evaluates to false. Note: Handling for w and ww was added in 2.25.0. In situations where you care about this (and only in those), you can separate your state and your state setters in two different contexts. Note: moment#endOf('week') was added in version 2.0.0. Invalid durations return NaN for all units. this Note: Moment#date is for the date of the month, and Moment#day is for the day of the week. Both don't need to be in the same provider. A variable declared without a value will have the value undefined. argument or after suffix arg: Note: Passing thresholds in humanize was added in 2.25.0. To change active locales, simply call moment.locale with the key of a loaded locale. Unfortunately, TypeScripts trees are concrete rather than abstract, and our architecture expects syntax tree node fields to be entirely ordered before or after each other. Locale#isPM should return true if the input string is past 12 noon. When TypeScript sees the binding pattern [a, b, c], it creates the type [any, any, any], and that type gets picked up as a low-priority candidate for T which also gets used as a hint for the types of [42, true, "hi!"] In my case, I added Lucid extension to Chrome and didn't notice the problem at that moment. For Typescript 1.x try adding "allowSyntheticDefaultImports": true in compilerOptions in your tsconfig.json file and then use the syntax. Note: There is a bug that prevents moment.locale from being loaded. The Moment prototype is exposed through moment.fn. Thus, it might make sense to continue using Moment throughout your project rather than including yet another date and time library. Note: It should be noted that moments are mutable. , TypeScripttargettargetstring, const x: Return<"not a function type"> = 3. See the Parsing Guide for additional information. Because never is the identity with respect to unions that type simplifies to { price: number }, which is what we want. If not provided, using the version from the OpenAPI specification file. This is useful wherever you need to have a human readable length of time. Use if Generic values also get narrowed similarly. As of version 2.12.0 it is possible to list all locales that have been loaded and are available to use: It is sometimes useful to get the list of months or weekdays in a locale, for example when populating a dropdown menu. @typedef comments already automatically export types from their containing modules. I am a software engineer in NYC with special interests in frontend programming and type-driven development. Double Extremely well explained! 2.16.0 deprecated using moment().dates(). We mentioned these briefly in the Basic Types section. Mutates the original moment by subtracting time. If a string does not match any of the above formats and is not able to be parsed with Date.parse, moment#isValid will return false. Imagine our UserContext in a big app. moment.duration().asDays() gets the length of the duration in days. false. A class that wraps a v8::Function handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution. // the value that will be given to the context, // this would usually be your own backend, or localStorage, // the Provider gives access to the context to its children, "useUserContext was used outside of its Provider", "useUserContextState was used outside of its Provider", "useUserContextUpdater was used outside of its Provider", // the Providers gives access to the context to its children, there are other strategies you can also use, Extract the React Context logic in another file, Be careful about updating context values, and memoize them, Separate state and state setters (if necessary), Only use React Context if you really need it, Share the authentication state across your app, Share a value that is used by a lot of components in a part of your app (for example the current balance of a user in a dashboard where a lot of components are using that balance). Specify Eras for a particular locale. These modules might have lots of exports that can pollute the auto-imports list and make it harder to navigate, and this option can help in those situations. Using this plugin allows you to format OA dates into JavaScript dates and vice-versa. It is also possible to set the zone from a string. Like moment#isAfter and moment#isBefore, any of the units of time that are supported for moment#startOf are supported for moment#isSame. Like moment#toNow, passing true as the second parameter returns value without the suffix. argument to the function. In the Page component, we are accessing the context by using the useContext hook directly. You can see the changes, along with the performance results on GitHub. range-related features and excels at formatting ranges readably. Use undefined. * `useDebugValue` can be used to display a label for custom hooks in React DevTools. When to use type vs interface?. Before You can follow the progress of Pipe Operator (|>) for JavaScript here: https://github.com/tc39/proposal-pipeline-operator. TypeScript 4.8 makes these an error unless theyre referenced later in the signature. For example, the user variable is an object. Like moment#isSame, moment#isBefore, moment#isAfter any of the units of To get the most out of this tutorial, you need a basic understanding of React and TypeScript. You may be familiar with this pattern from its use in jQuery. If the day of the month on the original date is greater than the number of days in the final month, Locale#week.dow should be an integer representing the first day of the week, 0 is Sunday, 1 is Monday, , 6 is Saturday. The resulting time is browser-dependent, either adjusting the time forward or backwards. After cleansing, the string is validated in the following space-separated sections, all using the English language: [*] See section 4.3 of the specification for details. Note: While these date formats are very similar to LDML date formats, there are a few minor differences regarding day of month, day of year, and day of week. format(). Doing this is the same as not updating the field at all: There are some caveats to filtering with conditionals which might produce unexpected results. be described as 501 BC, the 501st year from the BC era. * to add properties or an index signature of your own. Note: ECMAScript calls this a "Time Value". Finally, Moment will search intelligently through an array of locales and their substrings. Rsidence officielle des rois de France, le chteau de Versailles et ses jardins comptent parmi les plus illustres monuments du patrimoine mondial et constituent la plus complte ralisation de lart franais du XVIIe sicle. Thats really the only feature Im still hoping to see added to TypeScript, and I know you guys wont do it until the proposal advances. The type has also been changed to undefined so that existing tools know to handle them correctly. duration. As of version 2.13.0, Moment includes a typescript definition file. * * `useRef` returns a mutable ref object whose `.current` property is initialized to the passed argument false. Before 2.0.0, moment#diff returned a number rounded to the nearest integer, not a truncated number. It's a simple way to display both short and long versions of human-readable timestamps. The isFuture argument will be true if it is going to use the future suffix/prefix and false if it is going to use the past prefix/suffix. Previously, TypeScript assumed decorators would always be placed prior to all keywords/modifiers. Prisma Client differentiates between null and undefined:. Placed at the start of the duration representation. JavaScript has always had a Date object, defined ECMAScript (ECMA-262) specification here. invocation: sameElse is used as the format when the moment is more than a week away from the referenceDay. for best experience. + * Use `ts.getDecorators()` to get the decorators of a `Node`. handled precisely. But what if the component is not actually inside a UserContextProvider?. UTC can also be used to convert out of a fixed offset mode: Note: Unlike moment.fn.zone this moment-timezone. In many languages, operators like == perform whats called "value" equality on objects. For Typescript 2.x try adding "moduleResolution": "node" in compilerOptions in your tsconfig.json file. year numbering. * https://github.com/frenic/csstype#what-should-i-do-when-i-get-type-errors Another benefit to doing that is that it saves us an import. * ``` Then you should use a tool like From version 2.10.3, if any of the endpoints are invalid the result is the Note that if the string does not include 'Z', it must include the + or - character. For example, take the following code. Duncan Jan 13, 2020 at 11:06 It is optimized to ensure that two months with the same date are always a whole number apart. To specify So we can simply use if condition to do null or undefined checks. This is very similar to a type assertion and should only be used when you're absolutely sure that the value is of the expected type. We used a TypeScript 2.0. Check if a moment is before or the same as another moment. If you need UTC, then subsequently call .utc(), as in: You can create a Moment with a pre-existing native Javascript Date object. From version 2.14.0 a different one can be specified with the isFormat key. For consistency, do not use classes in the core compiler pipeline. To switch from UTC to local time, you can use moment#utc or moment#local. Dec 30 would have a different week-year than Dec 31. Be careful about deeply comparing large objects: it is an expensive operation. , HTMLInputElementDOM, useCallback, addnumber, useMemouseCallbackuseMemo, useContext, useContextcontextcontext, useReducerstate, reducerreducerstateaction useReducer , Counter, dispatchReact.Dispatch, eventinput clientXclientY The decoded JWT payload is available on the request via the auth property.. null You can assign null to a variable to denote that currently that variable does not have any value but it will have later on. So a.max(b) is the same as a = moment.min(a, b) (note that max is converted to min). If a locale requires additional processing for a token, it can set the token as a function with the following signature. And if you know that for some reason, your generic value cant be null or undefined, you can just use a non-null assertion. , JSX.Element React.createElement JSX , React React.ReactElementTT/, ReactElementtype,props,key null ReactElement Source. You can check the metrics used by #isValid using moment#parsingFlags, which returns an object. If instead you would like an ISO8601 string that reflects the moment's utcOffset(), then you can modify the toJSON function like this: Formats a string to the ISO8601 standard. As an example, consider that Moment objects are mutable. It's best to wrap it in a useCallback hook: Keep in mind that memoizing won't always prevent unnecessary triggers. * The index signature was removed to enable closed typing for style If you wish to squash that global, use the noGlobal option on the module config. and should only be used when you're absolutely sure that the value is of the TypeScript 4.8 introduces an editor preference for excluding files from auto-imports. If the range is exceeded, it will bubble up to the minutes. There are also special considerations to keep in mind when adding time that crosses over daylight saving time. Optional Chaining. The current direction of decorators in TC39 means that TypeScript will have to handle a break in terms of placement of decorators. Note: The length of a duration in weeks is defined as 7 days. This can be changed by replacing the moment.parseTwoDigitYear method. Prior to TypeScript 3.0 the best way to write prettyPrint would have been to use any for the type of x. days validity may depend on month, for example). * Note that `useRef()` is useful for more than the `ref` attribute. Tutorials on React and Javascript, updated weekly! The repository is located at github.com/SeverinDK/moment-timer. In general, you should create a locale setting with your customizations. Lets write some code that makes a network request, but that fails if the request takes too long. are non-work days. As of 2.3.0, moment also supports parsing ISO 8601 durations. This is parsed in the moment's current locale. Sometimes, you want all the goodness of moment#from but you don't want to As always, imperative code using refs should be avoided in most cases. With the above setup, you can require the core with moment and de locale One example would be: Existing code that didnt want to handle null and undefined can be fixed by propagating the appropriate constraints through. With the note that each call to getModifiers and getDecorators may allocate a new array. A modified moment (i.e. Note: From version 2.11.0, like Locale#months, Locale#monthsShort can be an object with standalone and format cases. Until the ss threshold is set, it defaults to the value of the s threshold minus 1 (so, invisible to the user). Accepts numbers from -270,000 to 270,000. We will not be addressing tree shaking or bundle size issues. *, /** For more complicated use cases please read excellent explanation by @jrburke. but TypeScript needs to figure out whether those two types should be Array or the tuple type [number, boolean, string]. The query receives filters from a formData object, which includes an optional email property. Much like moment#add, you can pass an object of values if you need multiple different units of measurement. Since our beta release, our stable release now has support for excluding which files are considered in auto-imports. Pseudo locales can be useful when testing, as they make obvious what data has and has not been localized. You must make a new compelling argument for locale changes with significant, non-anecdotal evidence to support your position. *. As of 2.13.0 you can pass a bool as the first parameter of the weekday functions. non-null assertion operator asserts to the type system that an expression is non-nullable, as in not null or undefined.Using assertions to tell the type system new information is often a sign that code is not fully type-safe. If you are in UTC mode, they will map to the UTC equivalent. The following table provides a high-level overview of how the different operators handle 0, 1 and n filters. the type of the passed in argument are not compatible. For example, take the following function. Note: moment#startOf('week') was added in version 2.0.0. where date-only forms (like "2020-09-14") are parsed as UTC, instead of local time as they would be by ISO 8601. It should always return a month name. #Truthy and Falsy Values in JavaScript Before we dive into the ?? As of 2.18.0, invalid durations are supported, similarly to invalid Argument of type 'string or undefined' is not assignable to parameter of type string, // const message: "Greetings" | undefined, // Error: Argument of type 'string | undefined' is not. Locale#weekdaysShort can be a callback function as well. Another common argument against using Moment in modern applications is its size. As with moment#day, if the range is exceeded, it will bubble up to other weeks. If you change that object through a setState, as far as useMemo is concerned the object is a new one (even if all the keys and the values are the same). You just have to choose to access the state or the state setters (or both). We believe that similar code in JavaScript is at best an early foot-gun for JavaScript developers, and at worst a bug in production code. Feb 28 to Mar 28 should be exactly 1 month. then first "AA-BB" is tried, then a naive solution would try "AA", but * `useReducer` is usually preferable to `useState` when you have complex state logic that involves You may want to display a moment in relation to a time other than now. Year, month, week, isoWeek, day, hour, minute, and second. When a parameter is marked as In the meantime, we hope that TypeScript 4.8 is a great release that makes coding a joy. If you need to access the locale data for a moment, this is the preferred way to do so. Sometimes the symptoms are stale or inaccurate errors that might show up that require restarting tsc or VS Code. Otherwise it's safe to go with the simpler option from above. false A time part can also be included, separated from the date part by a space or an uppercase T. Any of the date parts can have a time part. Moment.js also has duration objects. If the range is exceeded, it will bubble up to the months. You can pass in any month as the starting quarter, e.g. y), month (months, M), date (dates, D), hour (hours, h), minute (minutes, m), If the range is exceeded, it will bubble up to other weeks. points of the interval. This plugin will allow you to create length-based intervals (days, weeks, etc.) If you call moment#locale with no parameters, you get back the locale configuration that would be used for that moment. * function expensive () { } has been problematic and implemented inconsistently in the past. * T These shortcuts are essentially the same as the following. If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.
