That's not really a replacement for a real language and architecture-(VM or otherwise)-aware debugger.

Which is a problem, because all of that stuff is awful compared to the state of the art of modern desktop and mobile tooling.

Matter of opinion, I actually prefer to debug C-compiled-to-JS than C-compiled-to-native these days. Mainly because I can script debugging procedures directly in the JS source and just run them.

But sure, if you prefer gdb or such, then the web platform is not going to be a perfect match for you.
