> When W3Fools was launched in 2011, the state of documentation for developers was poor. This site documented many content errors and issues with the W3Schools website. The Mozilla Developer Network was around but it did not have much support at the time.
> Today, W3Schools has largely resolved these issues and addressed the majority of the undersigned developers' concerns. For many beginners, W3Schools has structured tutorials and playgrounds that offer a decent learning experience. Do keep in mind: a more complete education will certainly include MDN and other reputable resources.
MDN would greatly benefit from more soft documentation and a playground setup similar to W3Schools
Or not. MDN usually suits me fine.
Actually, I find TutorialsPoint https://www.tutorialspoint.com/ generally pretty good, if not lacking in some depth. They give a decent soft intro, though.
They've corrected most of the bad sample code.
