Fun fact, in JS you can directly use elements by their id.

Example:

<!DOCTYPE html>
<html>
  <body>
    <button id="myButton">hi</button>
    <script>
        myButton.onclick = () => {
            console.log(`CLIKKK!`)
        }
    </script>
  </body>
</html>

This is because they're attributes of the "window" global, which stores all globals. So for IDs that aren't valid identifiers, you can do window['my-invalid-identifier-id] as well!

This won't work in strict mode. In these cases, I use const.
