Hi, Erik!

A while loop is in almost all languages if not all. So a while loop is when you want something to happen untill something else does. Let's put it in a real life explanation. So it would be like this.

While nobody stops me I will continue walking. If they do stop me then this will happen.

Hope it helps a bit at least, you should search it up on google for more info :)
