arr-map

arr-map

Faster, node.js focused alternative to JavaScript's native array map.

Install

Install with npm:

$ npm install --save arr-map

Why use this?

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

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']
