date-fns VS dayjs

datefns is an alternative library that has a different philosophy. Rather than using a different type to represent dates, it has you continue using native dates, but provides tons of functions to do common tasks like parsing, formatting and date math.

Good job creating a library. I'd would only like to know what benefit this library provides over more established libraries, such as date-fns? https://date-fns.org/

date-fns is a lightweight library that works with built-in Dates and can perform arithmetic.

Definitely also worth mentioning is date-fns

We are using three libraries inside our projects, which are moment Moment.js, Day.js, and date-fns.

I'd consider using a library to help you out. Maybe something like https://date-fns.org, you could combine isBefore and isAfter to create a isInRange. Once you have that you can loop though your dateArr and for each entry, check if it's in any of your given ranges then increment the count.

OT: moment.js is deprecated, if u can, use date-fns.

Web-site:https://date-fns.org/ Github page: https://github.com/date-fns/date-fns Demo: – License: MIT Github stars: 22.8k Contribution guideline: Yes Date-fns provides the most comprehensive, yet simple and consistent toolset for manipulating JavaScript dates in a browser & Node.js. It works well with modern module bundlers such as webpack, Browserify, or Rollup. Date-fns is built using pure functions and always returns a new date instance instead of changing the passed one. With the support of an amazing community, date-fns has dozens of locales.

Here's an example that imports the dayjs NPM package from Skypack in a Deno script:

Notice: dayjs is also a way to determine whether a date is yesterday. see more: https://github.com/iamkun/dayjs/

My favorite has always been Day.js [0] - it is really small, has a very clean API, great documentation and does pretty much everything I want.

Using React with React Bootstrap for the configurator UI. dayjs for date handling, i18next for internationalization.

15. DayJs

With general-purpose languages like JavaScript, though, this kind of thing is trivially easy, either with the language alone or with the help of a third-party package to make things even easier --- one like Day.js, for example:

the breakdown is not complete, for example I needed to pull in a new library to get the localized first day of the week with Luxon (this differs based on locale)

Also I really don't recommend dayJS, its documentation is crap (for example this is the documentation of its timezone plugin: https://day.js.org/docs/en/plugin/timezone ) and is full of serious bugs that its developer does not respond to: https://github.com/iamkun/dayjs/issues

Also the code style is really concerning too: https://github.com/iamkun/dayjs/issues/1598
