Instead of adding several almost equal lines in a script we can use loops to perform a task like
The for loop is used when you know in advance how many times the script should run.
The example below defines a loop that starts with i=0. The loop will continue to run as long as

Note: The increment parameter could also be negative, and the <= could be any comparing
The while loop will be explained in the next chapter.
