arr-map NPM version

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

JavaScript's native Array.map() is slow, and other popular array map libraries are focused on browser compatibility. This implementation is focused on node.js usage keeping it light and fast.

Install with npm

npm i arr-map --save

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']
