When and how to use interfaces and classes in TypeScript

Interfaces and classes are crucial components of object-oriented programming (OOP) in TypeScript, a JavaScript language supporting these features from ES6 onwards. Classes act as blueprints for creating objects with specific properties and methods, allowing for type checking and clean JavaScript conversion. Interfaces, on the other hand, serve as contracts, defining method and field structures without implementation, primarily aiding in type checking during development. While classes are used to instantiate and manage objects, interfaces validate the structure of properties and enhance code readability without necessitating object creation. The combination of both can facilitate efficient coding practices, allowing developers to create robust applications by leveraging the strengths of each according to their specific needs.
