Classes and interfaces

TypeScript introduces classes and interfaces, two fundamental concepts from object-oriented programming, to enhance JavaScript's capabilities and bring it closer to other popular programming languages.

• Classes:

Classes provide a blueprint for creating objects, encapsulating data and behavior together. They enable developers to define properties and methods that can be shared among multiple objects, promoting code reusability and maintainability. TypeScript's classes also support inheritance, allowing developers to create hierarchical relationships between classes and reuse code across different levels of the hierarchy.

Interfaces define contracts that specify the properties and methods that a class must implement. They serve as blueprints for defining the shape and behavior of objects, ensuring consistency and promoting loose coupling between different parts of the code. TypeScript's interfaces also support multiple inheritance, allowing classes to inherit from multiple interfaces and combine their properties and methods.

The introduction of classes and interfaces in TypeScript brings numerous benefits to JavaScript development. These concepts enhance code organization, promote code reusability, and improve code maintainability. Furthermore, they facilitate collaboration among developers by providing a shared understanding of the structure and behavior of different components in the codebase.

To illustrate the usage of classes and interfaces in TypeScript, consider the following example: // Define an interface for a Person interface Person { name: string; age: number; } // Define a class that implements the Person interface class Employee implements Person { name: string; age: number; salary: number; constructor(name: string, age: number, salary: number) { this.name = name; this.age = age; this.salary = salary; } greet() { console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`); } } // Create an instance of the Employee class const employee1 = new Employee('John Doe', 30, 50000); // Call the greet method on the employee1 object employee1.greet(); In this example, the Person interface defines the properties and methods that a Person object must have. The Employee class implements the Person interface and adds an additional property (salary) and method (greet()). This demonstrates how classes and interfaces can be used together to create well-defined and maintainable code.

By incorporating classes and interfaces, TypeScript empowers developers to leverage object-oriented programming principles in JavaScript, leading to more structured, modular, and extensible codebases.
