TypeScript for Application Developers

What you’ll learn

• Make invalid states unrepresentable

  Model your domain so the compiler rejects the combinations that should never happen.

• Write real generics

  Build reusable functions and components that keep type information instead of erasing it.

• Use the type-level toolkit

  Apply conditional, mapped, and template literal types where they earn their complexity.

• Type the boundaries

  Validate and type the data crossing into your app, so external data stops being an any.
