Object-Oriented Programming (OOP) in TypeScript is explained by exploring language features and establishing the four fundamental principles: inheritance, polymorphism, encapsulation, and abstraction. The post discusses TypeScript constructs like classes, interfaces, and abstract classes, uses examples to illustrate key concepts, and emphasizes the importance of access modifiers and the benefits of OOP such as improved code organization and reusability.

<p>Nice article but when we parse JSON string to class object, all methods will be removed so that we need to manually create instance instead</p>


<p>This is a really clear and practical introduction to OOP in TypeScript. I appreciate how you walk through key language features—like classes, interfaces, inheritance, encapsulation—before showing how they embody the four OOP principles. Starting with concrete syntax and then connecting it to abstraction, polymorphism, and more makes the concepts stick. As a front‑end dev who’s used JS for years, having this bridge to structured, maintainable code in TS is exactly what I needed. Great guide!</p>
