Hands-On Introduction to Typed Programming with TypeScript

Welcome to Hands-On Introduction to Typed Programming with TypeScript — this is a practical, beginner-friendly course designed to help you understand and start using TypeScript in your real projects.

I’m Lucas, a tech lead working in an international team, and I’ve created this course to give you the tools and knowledge to work with TypeScript effectively — without overwhelming theory or unnecessary complexity. We’ll focus on hands-on examples, use cases, and clear explanations directly in the code editor as we will be able to see TypeScript in action right away.

Throughout the course, you’ll learn:

• How to set up TypeScript from scratch and understand its role in modern JavaScript development
• Working with type annotations, type inference, and built-in types
• Creating and using custom types, interfaces, and type aliases
• Understanding unions and literal types
• Leveraging functions, parameters and return types
• Exploring classes, access modifiers, inheritance, and interfaces
• Harnessing the power of generics for reusable, type-safe code

We’ll build and test everything step-by-step, so by the end, you’ll not only know how TypeScript works but also how to apply it confidently to your own projects.

So if you’re completely new to programming or an experienced JavaScript developer looking to level up, this course will help you write safer, cleaner, and more maintainable code with TypeScript.
