Callbacks nuances in JavaScript

Callbacks don't have to be anonymous functions. For example, let's say we have the following function:

javascriptfunction square(num) {
  return num ** 2;
}

Let's use it to square each element of the array:

javascriptfunction square(num) {
  return num * num;
}

let result = each([1, 2, 3, 4, 5], square);
console.log(result);

Use the following function to cube all the elements of an array:

javascriptfunction cube(num) {
  return num ** 3;
}
