TypeScript Classes Explained: OOP, Modifiers & Inheritance
TypeScript classes bring real object-oriented programming to JavaScript — with the safety of types baked in. In this beginner-friendly tutorial, you'll learn how to model real-world things using classes, control who can touch your data with access modifiers, and reuse code cleanly through inheritance. If you've ever felt confused about 'public', 'private', or 'extends', this video clears it all up step by step.
We start with what a class actually is and how it differs from a plain object. Then we build a real class from scratch — adding properties, a constructor, and methods. From there we explore access modifiers like public, private, protected, and readonly, parameter properties that save you typing, getters and setters, static members, inheritance with extends and super, abstract classes, and how classes can implement interfaces. Every concept is shown with real, runnable TypeScript code in a live editor.
