js-joda VS date-fns

js-joda

So first, a simple example of how this works. Using our "What is your birthday" example, we can mock up this code. Note: I'm using TypeScript because it enforces the concepts at compile time, but the JsJoda library itself enforces the concepts at runtime so that we get the best of both.

Dealing with human dates is non-trivial thanks to localization. The easiest thing to do is to start with something zone agnostic (like UTC or epoch) do your date calculation, and then shift that into the locale you want. date-fns is fine for basic date math, but if you want something more robust, with a more cohesive API, I'd recommend js-joda.

How come the js-joda library is never mentioned in discussions about javascript date/time libraries? its API is perfect and it has been around forever. but instead the community seems to keep inventing more and more new datetime libraries. i don't understand why js-joda seems to be ignored

I've been getting by with js joda. Temporal is a welcome addition.

Support for the domain models LocalDate, LocalDateTime, ZonedDateTime, Instant, Duration and Period. Also, supports IANA timezone, adding the plugin @js-joda/timezone you'll have access to the IANA timezone database with all the timezones available.

// Prevent the date to lose the milliseconds when passed to new Date() in IE10 return new (argument.constructor as GenericDateConstructor)( +argument, ); // Source: https://github.com/date-fns/date-fns/blob/5c1adb5369805ff552737bf8017dbe07f559b0c6/src/toDate/index.ts#L46

For the longest time working with dates in JavaScript was a huge pain. That’s why libraries such as moment.js or date-fns are so popular. A lot of times I’d reach for these libraries when working with relative time formatting, but since late last year we’ve had pretty great browser support for the RelativeTimeFormat() method. In my mind, relative dates are just more visually appealing, especially for working with dates internationally. Dates like "5 days ago" or "in 2 months" are far more intuitive for users than 12/12/2023, or 03/11/2027. Folks in the US will see that as March 11, 2027, whereas the rest of the world will see that as November 03, 2027. What a nightmare.

8. Date-fns - Simplifying Time Manipulation ⏳

I work with date-fns and date-fns-tz

In past i used Moment, but I read that we should avoid to use it for future projects. I read someone suggested to use Datejs, but it doesn't seems to be updated, last time was 8 years ago. Currently I'm thinking to use Luxon but I someone suggest Date-fns also.

date-fns : Date handling

Thanks! I used date-fns for the calendar

I've used this before and I like it more

The default date constructor does a really great job at parsing in most cases and things like addition/subtraction along with many other common operations are usually just simple math. If you really want to abstract that use date-fns where most date operations are tree shakable to be left with just a few lines of code.
