It is generally common knowledge that computers are great at performing repetitive tasks an infinite number of times, and doing so very quickly. It is also common knowlede that computers really don't do anything unless someone programs them to tell them what to do. Loop statements are the primary mechanism for telling a computer to perform the same task over and over again until aset of crieria are met. This is where ''for'', ''while'' and ''do ... while'' loops are of use.

Whilst this is somewhat cumbersome it does work. What would happen, however, if you needed to perform this task 100 times or 10,000 times. Writing a script to perform this as above would be prohibitive. This is exactly what the ''for'' loop is intended to handle.
