Plus if you are able to debug it somehow, and discover the bug in your code, can you fix it right there in your debugger? Or do you need to figure out what is the place in your original unprocessed source-code that corresponds to the code you see in the debugger, and then switch from the debugger to edit the original file and then rebuild and rerun everything and see if that fixes the problem? I wonder if that is a solved problem in plain TypeScript either?
