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.
