I found (on a team with a mix of VSC and WebStorm users) that VSCode had better overall support for jump to definition and refactorings: the refactorings, in particular, were more accurate and were less likely to change irrelevant locations or leave usages unchanged. Also, at the time, prettier integrated into VSC better: that may have changed since.

What? MS made TS, VS code is written in TS but somehow when it comes to TS, VS code doesn't work as good as JS?

I don’t know, I don’t really use or like Typescript. But, the reason I think IntelliJ may do better with Typescript is just that TS has a Java-like type system, so IntelliJ’s Design as a Java IDE may end up being an advantage.
