  1. 1

    TypeScript Fundamentals

    Not started

    TypeScript is JavaScript with a type system. The same code that runs in browsers, but the compiler catches errors before you ship. Static types, interfaces, generics — every lesson is hands-on with real ts-node execution.

  2. 2

    TypeScript Intermediate

    Not started

    Level up from TypeScript Fundamentals. Generics, union and intersection types, narrowing, mapped types, utility types. The features that make TypeScript's type system genuinely useful, not just JavaScript with annotations.
