Difference between two arrays in Angular JS

Question

Consider following arrays:

array1 = ['a','b'];
array2 = ['a','b','c','d'];

I need to extract the difference. So my resulting array should look something like,

array3 = ['c','d'];

If an element is present in array1 then it should be poped from array2. I am looking for solutions more angular way,is there any directive available?

There is a plain JavaScript answer available here: stackoverflow.com/questions/7669555/…: var c = array2.filter(function(item) { return array1.indexOf(item) === -1; }); — Carsten Massmann

In my opinion you can use underscore or lodash library for such tasks. for example in underscore you can done it through this simple code :

difference_.difference(array, *others)

Similar to without, but returns the values from array that are not present in the other arrays.

_.difference([1, 2, 3, 4, 5], [5, 2, 10]); => [1, 3, 4]
