I tried typescript lsp in emacs (tide) and it gave me a lot for free (realtime type check, formatting). What else VSCode has ? nicer hints (dom based) and refactoring ? Genuinely curious.
Also VSCode puts my poor laptop to its knees. Core i5 cannot handle few keystrokes in a row.. that was quite a shocker tbh.
From my observation, the IDE-parts of VS Code are what put most computers to their knees. VS is very performant when acting like a regular text editor, even better than emacs in certain cases -_-
But the moment the language-servers kick in and start analysing code and projects, the horror starts. It eats ram, cpu and grabs all attentions in can gain. Emacs can have those problems too, but there it's simpler to avoid those stuff. But to be fair, in VS Code to some degree you can deactivate it too it seems.
