This way you can use strings of any format you want and still comfortably use them with Moment.įor example, in the US (for some reason) we like to format our dates as "Month/Day/Year", whereas much of the rest of the world formats theirs as "Day/Month/Year". You provide the date-time string to be parsed and another string that specifies the format that it's in. It is basically like a reverse string formatter. One of my favorite parsing features in Moment is the string/format parser. For more information on time zones, check out the section Moment Time Zones. To get UTC times back, use moment.utc() instead. isValid() method: > moment( ' 09:30:26.123').isValid() įor all date objects created with Moment, no matter how you parse or create them, the time zone in the object will default to the current time zone, unless specified directly. To check if your date was parsed and valid, use the. If for some reason Moment isn't able to parse the string you gave it, then it will fall back to using the built-in new Date() object for parsing. To parse a date-time string with Moment, just pass it to the constructor: > let date = moment( ' 09:30:26.123') This will instantiate a date object with the current time. This is great for us since dates can take on many different forms, depending on the level of detail you want to specify.Ĭonsidering trying to parse all of these different formats on your own:Īs you can see, not only does the time precision change, but the format in which it is specified can widely vary, which is why it's so important to have a capable time parser.įirst off, the simplest way to create a moment object is to call the constructor with no arguments: > const moment = require( 'moment') You can specify as little, or as much, time precision as you want in your date-time using this format. Parsing Dates Stringsīy default, Moment attempts to parse date strings using the ISO 8601 format, which has a wide range of valid dates. In this article you'll see how Moment makes dates and times easy to parse, format, and manipulate. The standard JavaScript Date object isn't too bad, but it lacks some important features and isn't always simple to work with. However, dates aren't easy to work with, so it's important to have a library that is both accurate and has a simple interface. You might use dates for tracking the creation of an object, to track the time since an event occurred, or to save the date of an upcoming event. As any experienced programmer knows, dates and times are incredibly common in most application-level code.
