How to compare arrays in JavaScript?

Question

Can anyone help me how I can able to compare tow arrays in JavaScript? I tried with a comparison operator but it is not working.

Answer 1

Basically, in able to compare two arrays, first, we need to sort the array which will give the accurate result:

const array2Sorted = array2.slice().sort();

array1.length === array2.length && array1.slice().sort().every(function(value, index) {

    return value === array2Sorted[index];

});

This will first sort the array and then it gives the output as true.

I hope this will help.
