JarCastingarray-unique 
Remove duplicate values from an array. Fastest ES5 implementation.
Install
Install with npm:
$ npm install --save array-unique
Usage
var unique = require('array-unique');
var arr = ['a', 'b', 'c', 'c'];
console.log(unique(arr)) //=> ['a', 'b', 'c']
console.log(arr) //=> ['a', 'b', 'c']
/* The above modifies the input array. To prevent that at a slight performance cost: */
var unique = require("array-unique").immutable;
var arr = ['a', 'b', 'c', 'c'];
console.log(unique(arr)) //=> ['a', 'b', 'c']
console.log(arr) //=> ['a', 'b', 'c', 'c']
