This course is built for JavaScript developers ready to level up their code quality, collaboration, and safety. Starting with core types and inference, you’ll learn about interfaces, unions, generics, classes, utility types, and real-world patterns. You’ll model complex data, catch bugs at compile time, and write code that scales efficiently.
With interactive lessons, hands-on exercises, and a capstone project, you’ll develop both conceptual understanding and practical skills to use TypeScript like a pro. This course sharpens your skills in modern TypeScript and prepares you to build and maintain codebases in any environment.
