But here’s the thing. Are you really going to bother including a
file if you don’t need that file? In most cases, probably not. And
you’re including that file because you need it; you require that
file to run. So in almost every situation, you should use require
to grab another file, not include. If something goes wrong, you
want to know about it. You don’t want the rest of your code
running, because it’s probably just going to error out anyway.
