Yes, to me this is a biggest feature of Typescript: A little goes a long way, while the advanced features make really cool things possible. I tend to think of there being two kinds of Typescript - Application Typescript (aka The Basics, `type`, `interface`, `Record`, unions etc...) and Library Typescript which is the stuff that eg Zod or Prisma does to give the Application Typescript users awesome features.

While I aspire to Library TS levels of skill, I am really only a bit past App TS myself.

On that note I've been meaning to the the Type-Level Typescript course [0]. Has anyone taken it?
