> I'm editing TS perfectly fine in Jetbrains IDEs, and some coworkers use emacs and vim without any issues, still getting all the error highlights, etc.

That's why you don't have any issues. The error popups aren't the problem. It's the autocomplete and type popups.

The last few years TS has raised an army of shit devs that code in such a way that it's literally impossible to read the code without your IDE popping up multiple boxes to tell you what is happening. They just search every function name, giving zero thought to where anything lives in the directory structure. They type everything like fucking idiots, with layers upon layers of types across 10+ files, all of which you have to open just to find out you're working with an object that has a couple of strings and a number on it. Of course VSCode will just tell you this when you hover over the variable, if you're using it.

Just wait until you get a project where these muppets have a majority and you'll feel the pain.
