VSCode and other IDEs can do . completion, go to def, rename, etc on plain JavaScript. That's not a unique feature of typed languages.

But find all references doesn't actually work without typescript if your data is passed around enough, and that's an important one for refactoring.

No they don't. They can make a decent guess occasionally but it's not remotely the same as in typed languages where it's accurate and works all the time.

It is absolutely a unique feature of typed languages.
