6 While Loop vs For Loop For loops are forcing the computer to loop a certain set of code a specific set of times. It is possible that code can run into an error if that number is too small or too large. A while loop doesn’t place an exact number necessarily, rather has a procedure repeat until something interrupts it. While loops are similar to If statements because they repeat until a certain condition is met.
