When you perform a loop it makes programming a lot easier because if you have to write multiple lines of code that are the same it can take precious time and energy that you don't need to waste your time and energy. Just make a loop! We make them if we want to repeat something and we should use a loop only when you need to. If you have to repeat a line of code once you don't need to use a loop, but if you need to repeat the line of code lets say, 10 times you can use a loop.
Hope this helps,
