As someone who's done webdev for a living since 1998, I share the OP's distaste for w3schools -- they truly earned their notoriety as a low-quality, spammy, SEO-hacking parasite. It was so bad it inspired a large group of some of the biggest names in the field to push back with a site called "w3fools" that tried to set the record straight and steer the hapless masses away from w3schools. See eg https://web.archive.org/web/20110412103745/http://w3fools.com/ https://web.archive.org/web/20110412103745/http://w3fools.co... Unfortunately, it seems w3schools has since managed to acquire the w3fools domain, and (facepalm, what the actual f**) have appropriated the original content to make it appear as if those famous anti-w3schools signatories have all changed their minds and now endorse w3schools (!) -- which might actually be libel? and is just another scandalous example of the shadiness at play. A leopard doesn't change its spots. w3schools sucks. Steer clear!
