When comparing two arrays in JavaScript, one has to compare the lengths of arrays and the elements of the arrays. Here's an example:

function areArraysEqual(arr1, arr2) {
  if (arr1.length !== arr2.length) return false; // Different lengths
  return arr1.every((value, index) => value === arr2[index]); // Compare elements
}

const array1 = [1, 2, 3];
const array2 = [1, 2, 3];
console.log(areArraysEqual(array1, array2)); // Output: true

This method works only when the array to be sorted contains primitive values. If operations are performed on more complicate arrays or objects, then one would have to use deep comparison methods.

If you're interested in learning more about arrays in JavaScript, here is our guide.
