How to compare two arrays in node js?

Question

I am having two arrays, how can i compare the two arrays at single shot.

   var arr1= [\"a\",\"b\",\"c\"];
   var arr2 = [\"a\",\"c\",\"d\"]

   if(arr1 == a         


        

Answer 1

I would like to improve the answer from staackuser2 a little bit:

var same = (arr1.length === arr2.length) && (_.difference(arr1, arr2).length === 0)

or

var same = (_.difference(arr1, arr2).length === 0) && (_.difference(arr2, arr1).length === 0)
