I find it very hard to read through MDN Docs

This is interesting because MDN is, IMO, some of the better documentation out there. Just take it slow. I'm at 10 years and even I, looking at a giant article, feel a bit overwhelmed. But like everything in this trade, take it piece by piece. More on reddit.com

MDN documentation is not the easiest to understand for beginners, because it's more of a spec than a hand-holding guide. More on reddit.com

Mozilla have laid off the entire MDN writers team. What's the best MDN alternative now it is likely to drift out of date?

Not just the MDN team, but the dev tools team and what was left of the developer relations team too. Mozilla had some incredible people but the higher-ups have really shown what they think of the importance of the developer community – often their biggest advocates. Hard to support them after this.

Yeah it's a great resource. Also I'd recommend anyone to read about html elements and other basic features. There's a ton of useful elements and attributes that even many experienced develooers are unaware of. Not to mention many JavaScript features that modern JS has.
