I came to VSCode from TextMate, so my expectations were minimal, but I can’t think of anything more to wish for from its completion and auto-imports. I’m generally using it for TypeScript which is probably its strongest use case. But even untyped JavaScript is pretty good: local type inference is alright, JSDoc types nearly on par with TS, automatic type acquisition for dependencies is better than manual installation in TS.

That said, it’s been years since I tried IntelliJ. Am I missing some significant productivity improvement, for TS/JS development?

Given that VSCode is built in TypeScript, and it existed primarily for JS/TS in the beginning this is expected. You don't get whole lot of more from JetBrains/Fleet in that case.

Usually though JetBrains' editor is used by other languages, which don't yet have as good open language servers, like Java/Kotlin/Scala/C#...

A colleague of mine and I tried to asses VS Code vs. Intellij IDEA for vanilla JS & Typescript + Vue. Him a heavy VS user, me more at home with Intellij. In both cases we concluded Intellij proved superior, though both were usable.
