JavaScript Callback Functions in JavaScript Callbacks with Timers Using a One-Off Timer with setTimeout

Why do we not put brackets next to callback functions again? It is because the function is invoking it and not us?

I assume you mean "parentheses" instead of "brackets", but you're exactly right. If you put parentheses after the function, it gets invoked and the result would be passed as the argument instead of the function itself.
