map vs forEach
Why did we loop with map and not forEach? Does it make any difference in the context of this exercise?
I think my issue here is understanding the difference between map and forEach

The difference between
map is the handling of return values. The
map method builds a new array made of the return values from the callback and then returns that array, while
forEach ignores any return value from the callback and its own return is undefined.
map when your callback returns a value, and you will use an array made up of those values.
