JavaScript's native `Array.map()` is slow, and other popular array map libraries are focused on browser compatibility, which makes them bloated or less than idea for non-browser usage. This implementation is focused on node.js usage keeping it light and fast. ## Usage ```js var map = require('arr-map'); map(['a', 'b', 'c'], function(ele) { return ele + ele; }); //=> ['aa', 'bb', 'cc'] map(['a', 'b', 'c'], function(ele, i) { return i + ele; }); //=> ['0a', '1b', '2c'] ``` ## About ### Related projects * [arr-diff](https://www.npmjs.com/package/arr-diff): Returns an array with only the unique values from the first array, by excluding all… [more](https://github.com/jonschlinkert/arr-diff) | [homepage](https://github.com/jonschlinkert/arr-diff "Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons.") * [arr-filter](https://www.npmjs.com/package/arr-filter): Faster alternative to javascript's native filter method. | [homepage](https://github.com/jonschlinkert/arr-filter "Faster alternative to javascript's native filter method.") * [arr-flatten](https://www.npmjs.com/package/arr-flatten): Recursively flatten an array or arrays.
