It's not a question, rather suggestion. You shouldn't use w3schools reference.

28,147 PointsYes, you are correct. There are some errors and omissions, and thus they don't have a great reputation, so in general, no you shouldn't use them as a reference. I've personally come across outdated or now incorrect information there. Mozilla's MDN is a fantastic source: https://developer.mozilla.org/en-US/ as well as the official W3 documentation, but that's enough to make anyone's eyes glaze over.
I think most developers give grace to entry developers who reference their documentation, but it's best to not reference them to make a point.
