There are only five important languages with native compilation and IDE backing in my opinion:
C, C++, Objective-C, Delphi/Object Pascal, and Swift.
I understand your bias towards native languages, given your specialty. I would also add the Rust language to this list.
JetBrains is too heavy on virtual languages like Java after my fancy.
That is true. It is entirely written in Java, indeed. But the surprising thing is that they managed to make it work even faster than Visual Studio in some cases.
The fact that the language is not native is not such an issue for many types of applications. Most often, problems are caused by an architecture, not the tooling and languages.
