js array comparison code example
Example 1: javascript compare arrays
Array.prototype.equals = function(arr2) {
return (
this.length === arr2.length &&
this.every((value, index) => value === arr2[index])
);
};
[1, 2, 3].equals([1, 2, 3]);
[1, 2, 3].equals([3, 6, 4, 2]);
Example 2: compare arrays javascript
const array1 = [1,2,3,4]
const array2 = [1,2,3,4]
array1.join() === array2.join()
const array3 = [1,2,3,[1,2,3]]
const array4 = [1,2,3,[1,2,3]]
JSON.stringify(array3) === JSON.stringify(array4)
