A tiny, faster alternative to native Array.prototype.map
npm install @arr/map> A tiny, faster alternative to native Array.prototype.map
:warning: Unlike native, @arr/map does _not_ support the optional thisArg parameter!
:warning: Unlike native, @arr/map does _not_ respect Array holes -- you probably never needed this... :thinking:
``
$ npm install --save @arr/map
`js
import map from '@arr/map';
const nums = [1, 5, 10, 15];
const doubles = map(nums, x => x * 2);
//=> doubles is: [2, 10, 20, 30]
//=> numbers is: [1, 5, 10, 15]
