You don’t need loops, please skip this section.
Ok fine, loops are useful when you want to do something more than once.

A simple loop could be like this:

<pre>for(i = 0; i<5; i++){
   /*this area will be executed 5 times, 
   once with i as 0, then 1 etc until finally when i is 4*/
}</pre>

Lets say, in the “go away” example the closer they get the more you want to say go away, lets say one exclamation mark for every meter they get towards you. A loop can do that.

<pre>distanceAway = W
permittedDistance = 10
if(distanceAway < permittedDistance){
    message = "Go Away"
    exclamationMarksToShow = permittedDistance - distanceAway //closer they get the more exclamation marks

    for( i = 0; i < exclamationMarksToShow; i++){
        message = message + "!"
    }
    N = message
}</pre>
