How to sort the new array?

Question

JavaScript

Good afternoon!
Can you tell me how to add a new array element to an array and sort all the elements of the new array?

It is possible both on ES5, ES6, and on jQuery.

Answer 1

So what?

const arr = [4, 63, 3, 87];

console.log(arr.sort((a, b) => a - b));

arr.push(2);

console.log(arr.sort((a, b) => a - b));

Answer 2

How to sort? On what basis?
Briefly, then

arr.push(elem)
arr.sort()
