@arr/map

@arr/map

A tiny, faster alternative to native Array.prototype.map

Unlike native, @arr/map does not support the optional thisArg parameter!

Unlike native, @arr/map does not respect Array holes -- you probably never needed this...

Install

$ npm install --save @arr/map

Usage

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]
