I know it’s not a popular opinion, but I actually like W3schools. Most of their infamous errors are gone and they are usually more “to the point” than Mozilla docs, which are a sometimes too prolific and not as clear.
It's "to the point" in the sense of being a more concise basic introduction. But MDN hits the right balance of being comprehensive yet accessible in a way nothing else does.
Plus W3Schools' very name is an SEO hack, so their Google rank is built upon fundamental dishonesty.
I actually have a couple of bash scripts just for this when I want to look something up specifically at mdn, and thought about expanding it to stack overflow and reddit.
What's that? Why yes I have heard the phrase 'bikeshedding', why do you ask? ;)
I like W3schools too, you're correct it's better these days. The site has helped me a lot when I needed to quickly get help usually with CSS or HTML. I like the "try it yourself" feature, and the examples are usually good. Not sure how good it is for JS and Jquery, I usually use Jquery.com and stackoverflow for JS.
The biggest problem with that site is that it's sometimes good. Sometimes. I never know that before I click if the required info is there or not or it's good enough or still relevant. With MDN my expectations are high but they are always matched.
That's why I installed the W3Schools removal chrome extension :)
