# lodash [Site](https://lodash.com/) | [Docs](https://lodash.com/docs) | [FP Guide](https://github.com/lodash/lodash/wiki/FP-Guide) | [Contributing](https://github.com/lodash/lodash/blob/master/.github/CONTRIBUTING.md) | [Wiki](https://github.com/lodash/lodash/wiki "Changelog, Roadmap, etc.") | [Code of Conduct](https://code-of-conduct.openjsf.org) | [Twitter](https://twitter.com/bestiejs) | [Chat](https://gitter.im/lodash/lodash) The [Lodash](https://lodash.com/) library exported as a [UMD](https://github.com/umdjs/umd) module. Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli): ```shell $ npm run build $ lodash -o ./dist/lodash.js $ lodash core -o ./dist/lodash.core.js ``` ## Download * [Core build](https://raw.githubusercontent.com/lodash/lodash/4.17.10-npm/core.js) ([~4 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.17.10-npm/core.min.js)) * [Full build](https://raw.githubusercontent.com/lodash/lodash/4.17.10-npm/lodash.js) ([~24 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.17.10-npm/lodash.min.js)) * [CDN copies](https://www.jsdelivr.com/projects/lodash) [](https://www.jsdelivr.com/package/npm/lodash) Lodash is released under the [MIT license](https://raw.githubusercontent.com/lodash/lodash/4.17.10-npm/LICENSE) & supports modern environments.<br> Review the [build differences](https://github.com/lodash/lodash/wiki/build-differences) & pick one that’s right for you. ## Installation In a browser: ```html <script src="lodash.js"></script> ``` Using npm: ```shell $ npm i -g npm $ npm i lodash ``` Note: add `--save` if you are using npm < 5.0.0 In Node.js: ```js // Load the full build. var _ = require('lodash'); // Load the core build. var _ = require('lodash/core'); // Load the FP build for immutable auto-curried iteratee-first data-last methods. var fp = require('lodash/fp'); // Load method categories. var array = require('lodash/array'); var object = require('lodash/fp/object'); // Cherry-pick methods for smaller browserify/rollup/webpack bundles. var at = require('lodash/at'); var curryN = require('lodash/fp/curryN'); ``` Looking for Lodash modules written in ES6 or smaller bundle sizes? Check out [lodash-es](https://www.npmjs.com/package/lodash-es). ## Why Lodash? Lodash makes JavaScript easier by taking the hassle out of working with arrays,<br> numbers, objects, strings, etc. Lodash’s modular methods are great for: * Iterating arrays, objects, & strings * Manipulating & testing values * Creating composite functions ## Module Formats Lodash is available in a [variety of builds](https://lodash.com/custom-builds) & module formats. * [lodash](https://www.npmjs.com/package/lodash) & [per method packages](https://www.npmjs.com/search?q=keywords:lodash-modularized) * [lodash-es](https://www.npmjs.com/package/lodash-es), [babel-plugin-lodash](https://www.npmjs.com/package/babel-plugin-lodash), & [lodash-webpack-plugin](https://www.npmjs.com/package/lodash-webpack-plugin) * [lodash/fp](https://github.com/lodash/lodash/tree/npm/fp) * [lodash-amd](https://www.npmjs.com/package/lodash-amd)
