TypeScript’s type system is uniquely powerful, but most developers only scratch the surface of what it can do.

In this code-driven session, you’ll explore some of the weirdest and coolest features of TypeScript: from the infer keyword and recursive types to using types for arithmetic and even recreating Wordle entirely with Typescript types.

You’ll discover fascinating tricks that might seem extreme and nerdy, and wonder when you’d ever need them. Spoiler: maybe rarely; but sometimes, these quirks can come in especially handy. More importantly, it’s just plain fun to explore the limits of TypeScript’s type system.
