JavaScript

using JS to do component composition

The instructor challenged us to create a component for the counter. I was able to do that and included it into Player component like this:

{ Counter() };

I basically applied the concept that anything inside the brackets is JS, so I was just calling a function inside another function.

Is this ok or not? should I just stick to self-closing tags?

You can add any JS expressions inside the curly braces in React, so yes, you can call a function or make calculations etc. Would need to see your code to see if there is a better way of doing what you are doing.
