array-uniq 

Create an array without duplicates

It's already pretty fast, but will be much faster when Set becomes available in V8 (especially with large arrays).

Install

$ npm install --save array-uniq

Usage

js
const arrayUniq = require('array-uniq');

arrayUniq([1, 1, 2, 3, 3]);
//=> [1, 2, 3]

arrayUniq(['foo', 'foo', 'bar', 'foo']);
//=> ['foo', 'bar']
