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).
$ npm install --save array-uniq
const arrayUniq = require('array-uniq');
arrayUniq([1, 1, 2, 3, 3]);
//=> [1, 2, 3]
arrayUniq(['foo', 'foo', 'bar', 'foo']);
//=> ['foo', 'bar']MIT © Sindre Sorhus
