A tiny, faster alternative to native Array.prototype.map
npm install map-arr> A tiny (124b), faster alternative to native Array.prototype.map!
JavaScript's native Array.prototype.map is (unfortunately) *much slower than standard for-loops.
This module has no dependencies and serves as a drop-in replacement for Node.js _and_ the browser!
It is ES3-compatible, which means it will run on _any_ browser and be the fastest version you can use.
Lastly, it is CommonJS & ES-Module friendly :tada:
``
$ npm install --save map-arr
`js
// import mapArr from 'map-arr';
const mapArr = require('map-arr');
mapArr(['foo', 'bar', 'baz'], el => {
return el + el;
});
//=> ['foofoo', 'barbar', 'bazbaz']
mapArr(['foo', 'bar', 'baz'], (el, idx) => {
return el + idx;
});
//=> ['foo0', 'bar1', 'baz2']
`
This module is a drop-in replacement for Array.prototype.map, which means it has the same API and behavior!
