Yeah MDN is the de-facto reference guide for web frameworks. W3schools feels like beginner tutorials. For me, I want “what happens if I pass undefined as the second arg to this function” and w3schools doesn’t answer that. It’s fine as a site, I suppose, it was insane when it outranked more complete websites. Off topic I see this more and more with Stackoverflow where semi-related questions outrank official docs.
