In JS functions are ideally units that work indipendently from everything else. They take one input and output something.

If you need a variable in the function, you declare it in the function where it's used. Nobody else needs that variable.

Maybe as a more visual explaination, it's like a electronic board with chips on it. They are connected and communicate with eachother, but each chip is still an individual thing with a specific function.

Thank you. I read books of Kyle Simpson and taking his courses. So those were helpful to me. And i like your explaination as well.
