While Loop
While-loops are code blocks that are executed multiple times as long as the specified condition is met.
The behaviour of while-loops is very similar to do-while-loops, and in some cases it even might be better to use do-while than while-loops, so watch out for opportunities to replace while-loops with do-while loops.
