It's like Lodash for dates

• It has 200 functions for all occasions.
• Modular: Pick what you need. Works with webpack, Browserify, or Rollup and also supports tree-shaking.
• Native dates: Uses existing native type. It doesn't extend core objects for safety's sake.
• Immutable & Pure: Built using pure functions and always returns a new date instance.
• TypeScript: The library is 100% TypeScript with brand-new handcrafted types.
• I18n: Dozens of locales. Include only what you need.
• and many more benefits

import { compareAsc, format } from "date-fns";

format(new Date(2014, 1, 11), "yyyy-MM-dd");
//=> '2014-02-11'

const dates = [
  new Date(1995, 6, 2),
  new Date(1987, 1, 11),
  new Date(1989, 6, 10),
];
dates.sort(compareAsc);
//=> [
//   Wed Feb 11 1987 00:00:00,
//   Mon Jul 10 1989 00:00:00,
//   Sun Jul 02 1995 00:00:00
// ]

The library is available as an npm package. To install the package run:

npm install date-fns --save
