I think that some have utilized JS too much, and never noticed that the web got slower because of it. Many have forgotten what HTML and CSS are good for, and some build pages that are nothing but a bit of JS to async load their markdown authored blogs. (It's asynchronous, that makes it soooo fast!) On the other hand, I'm genuinely pleased by features of APIs that are accessible with JS (like WebGL), rather than JS itself.
