Question

Looking for a function in underscore.js that will take 2 arrays and return a new array of unique values? Something like _without

_.without([0, 1, 3, 9], [1, 3])         


        

Answer 1

The _.difference function should give you what you're looking for:

_.difference([0, 1, 3, 9], [1, 3]); // => [0, 9]
