JS fans said the same thing years ago, claimed that it didn't need classes, more extensive core library, or better syntax. Then came ES6, almost a different language, and they magically changed their opinions to match. Apparently all those features they dissed were needed and good. After seeing this kind of switch-a-roo several times I realized that most of JS community have no fucking clue. They will gladly consume and defend absolutely anything they currently consider "theirs" and "modern". It's a matter of fashion and identity rather than language and tooling quality.

JS was and is a horribly designed programming language. The Web would be lightyears ahead of its current sorry state if the core language was a dialect of List of Smalltalk.
