Does TypeScript support all object oriented principles?

Câu trả lời

Yes, TypeScript supports all the core principles of object-oriented programming (OOP). These principles include encapsulation, inheritance, polymorphism, and abstraction. Each of these principles plays a vital role in the structure and behavior of object-oriented systems, and TypeScript provides robust support for implementing them.

  • Encapsulation is the principle of bundling the data (attributes) and methods (functions) that operate on the data into a single unit or class and restricting access to some of the object's components. TypeScript supports encapsulation through its class syntax and access modifiers like private, protected, and public[1][2][3][5][6][7][8].

  • Inheritance allows a class to inherit properties and methods from another class. In TypeScript, classes can extend other classes, allowing them to inherit properties and methods from the base class. This is achieved using the extends keyword[1][2][3][5][6][7][8].

  • Polymorphism is the ability of objects of different classes to respond to the same method call in different ways. TypeScript supports polymorphism through interfaces and class inheritance, allowing methods to be implemented or overridden in derived classes[1][2][3][5][6][8].

  • Abstraction involves hiding the complex im...
