TypeScript. Object-oriented programming (OOP)

Short summary

Learn object-oriented programming in TypeScript through comprehensive code examples. Topics include class definitions with type safety, access modifiers (private, public, protected, readonly) to control property visibility and modification, getters and setters for encapsulation, abstract classes for enforcing method contracts, interfaces for polymorphic design, and static methods for class-level shared state. Each concept builds progressively with practical, runnable examples.

• •TypeScript classes support type annotations for type-safe properties and parameters
• •Access modifiers (private, public, protected, readonly) control visibility and mutability of class members
• •Abstract classes and interfaces enforce design patterns—abstracts require implementations, interfaces enable polymorphism
• •Getters, setters, and static members provide encapsulation and class-level state management
