Then when someone calls that out, they shouldn't comment if they don't work with Javascript?
Which one is it, best in class JS editor (which yepthatsreality actually agreed to), or best in class IDE (but only people who work on JS can comment on that...)?
There is never "Just Best". Its always very much subjective. And speed is not always everything, as long as it is fast enough. And for example.. For me, my use case, emacs is best. It can do anything. It is best as Swiss Army knife, because it can do anything. JS IDE? Sure here. Clojure? Here you go boss. Haskell? Hell yeah. Especially, since introduction of LSP stuff (Emacs LSP and Eglot). Simultaneously it can do IRC, note taking, literate programming, statistics, and much more, like remote editing with TRAMP. So in that case, it is best.
But is it best as just Java IDE? Absolutely not.
