How to add a class and remove this class from other elements?

Question

JavaScript

Hey! Need help. There are several elements. I click on one element - a class is added to it. I click on another element - a class is added to it, and this class is removed from the first element. Etc. And if I click on an element that already contains our class, then this class is removed from it.
