The short answer is that create-react-app has the “noEmit” setting set to “true” by default.
The tsc command used by itself will look for the tsconfig.json file in the current and parent directories.

This sounds similar to compilation done in the C language by the gcc command. But it’s not the same.
The purpose of “noEmit” is to only use Typescript for type checking and nothing else.
