how can i compare two arrays javascript code example

Example 1: es6 compare two arrays

let difference = arrA.filter(x => !arrB.includes(x));

Example 2: javascript Compare two arrays regardless of order

const isEqual = (a, b) => JSON.stringify(a) === JSON.stringify(b);

// Examples
isEqual([1, 2, 3], [1, 2, 3]);      // true
isEqual([1, 2, 3], [1, '2', 3]);    // false
