remove common elements of two arrays in jquery

Question

I want to remove common elements of two arrays in jquery. I have two arrays:

A = [0,1,2,3]
B = [2,3]

and result should be [0, 1]

Answer 1

Checkout the library underscore.js.

Say you have two arrays,

var a = [0,1,2,3];
var b = [2, 3];

First find the union.

var all = _.union(a, b);

Then find the intersection.

var common = _.intersection(a, b);

The final answer should be the difference between the union, and the intersection.

var answer = _.difference(all, common)
