Adding types can prevent errors, clarify code, and speed up development. This session covers examples where using the right types helped achieve all of that.

We'll start with the fundamentals: union types, string template literals, type narrowing, and discriminated unions.

Next, we'll dive into type operators to create complex types from simpler ones. You'll learn how to manipulate and combine types.

Finally, we'll explore advanced TypeScript concepts like generics and conditional types. You'll learn how to create reusable type definitions for reliable and flexible code.
