About this course

Structural typing and assignability, generics in depth, conditional and mapped types, infer, template literal types, declaration files and module resolution. Then a typed API in Node, a React client, and one shared package both import, so renaming a field breaks the build on both sides before anything runs. Testing including the types themselves, building, publishing, and why a large codebase makes the editor slow.
