I think you have a great point there. Javascript and browser APIs has been changing a lot and so best practices change a lot. I am not sure why it is taking so long for things to gel in JS/DOM land though. My best guess is that it is because JS is essentially the only programming language that can be used in the browser. Programmers coming from a myriad of different language backgrounds have to use it and they use it in ways that make the most sense to them. If you're a python dev you still have to use JS on the front-end. If you're a PHP dev still gotta use JS. etc. etc. It is all things to all people and thats not easy.
