jsconfig.json - checkJs and exclude not working together nicely

[brownbl1]

Issue Type: Bug

I have a jsconfig.json that looks like:

My goal is to achieve the equivalent of adding //ts-check to all js files in my project. I also have some .jsx files I want to exclude, but even if I add the **/*.jsx pattern to the exclude section, I still get errors and squiggles in my jsx.

If I add // @ts-nocheck to this file, it removes all errors and squiggles.

But I know the exclude config section is doing something, because if I omit it I get many more errors that I didn't have otherwise.

So in summary, it seems that there is a bug here in that the exclude option does not function in quite the same way as // @ts-nocheck.
