# ECMAScript Modules **date-fns** v2.x provides support for [ECMAScript Modules](http://www.ecma-international.org/ecma-262/6.0/#sec-modules) that enables tree-shaking for bundlers, like [rollup.js](http://rollupjs.org) and [webpack](https://webpack.js.org). If you have tree-shaking enabled in your browser, just import functions normally: ```javascript import { format, parse } from 'date-fns' import { enUS, eo } from 'date-fns/locale' import { addDays, addHours } from 'date-fns/fp' ``` In TypeScript, now you can import individual functions in more idiomatic way: ```typescript // Before import * as format from 'date-fns/format' // Now import format from 'date-fns/format' ```
