Concatenates two arrays, removing duplicates in the process and returns one array with unique values.

var concat = require('unique-concat');
var res = concat([ 1, 2, 3 ], [ 1, 2, 3, 4, 5, 6])
console.log(res);
// => [1, 2, 3, 4, 5, 6] 
npm install unique-concat

Works only with types that can be properly hashed, which means that they need to have a sensible .toString() implementation

Types that work as expected: int, string

Types that work with caveats: float (if one float is part of the array, all numbers are converted to string)

Types that don't work: object since obj.toString === '[ object ]' for all objects.
