TSConfig Reference
Option-by-option documentation of tsconfig.json from the TypeScript team: strictness flags, module resolution, emit, JSX, interop and project references, each with examples, defaults and the version that introduced it. Use it to configure a project deliberately rather than copying someone else's file.
Type Challenges
Around 190 puzzles solved purely in the type system, graded warm-up through extreme, each with an online judge and published community solutions. Working through them builds real fluency with conditional types, infer, recursion and template literal types.
Total TypeScript: Essentials
The best single guided path from 'I know JavaScript' to 'I am confident in TypeScript'. Editor-first method: it teaches you to read tsc's error messages and use hover types as the feedback loop, which is the transferable skill. Matt Pocock's sixteen-chapter book, free to read in full online, taking a JavaScript developer through annotations, unions, narrowing, objects, classes, modules, generics and tsconfig setup. Finish it and you can type a React or Node codebase unaided.
The TypeScript Handbook
The official documentation written by the language team: everyday types, narrowing, functions, objects, generics, conditional and mapped types, modules and project configuration. After reading it you can annotate code and read compiler errors without guessing.
