Alternative code for Array.push() function

Question

I've been told not to use push in my coursework, as we are only allowed to use code we have been taught, which I find ridiculous.

I have written over 200 lines of code incorporating the push function multiple times. Is there a simple code alternative to the push function which I can implement for it?

Nowadays you can use array destructuring:

let theArray = [1, 2, 3, 4, 5];
theArray = [
  ...theArray,
  6,
];
console.log(theArray);

If you want to push several elements, put them at the end of the array. You can even put elements at the beginning of the array:

let theArray = [1, 2, 3, 4, 5];
theArray = [
  -1,
  0,
  ...theArray,
  6,
  7,
  8,
  9,
  10
];
console.log(theArray);
