How to check if two arrays are equal with JavaScript? [duplicate]

Answer 1

For primitive values like numbers and strings this is an easy solution:

a = [1,2,3]

b = [3,2,1]

a.sort().toString() == b.sort().toString() 

The call to sort() will ensure that the order of the elements does not matter. The toString() call will create a string with the values comma separated so both strings can be tested for equality.
