underscore.js - Determine if all values in an array of arrays match

Question

I have an array of arrays, which looks something like this:

[[\"Some string\", \"Some other string\"],[\"Some third string\", \"some fourth string\"]]
         


        

Answer 1

Use underscore to determine the difference between the two, and check the length of the array. An easy way to do this would be:

_.isEmpty(_.difference(array1, array2)) && _.isEmpty(_.difference(array2, array1))

This will return true if they are the same and false if they are not.
