If we run TSC watch, then we can just run it in watch mode, found zero errors, and you'll notice that nothing actually happens inside the folder. There's no JavaScript files being created. There's no dist folder being created.

00:38 So your job here is to work out why this is happening and to go first of all into the tsconfig.json. This was generated for us by VEET, and your job is to work out which of these config options could possibly be causing TypeScript to not emit any JavaScript

00:57 and why on earth we would actually want to do that. Good luck.
