Classes and interfaces are structures that promote both object-oriented programming and also type-checking in TypeScript. While a class is a blueprint from which you can create a group of objects sharing the same configuration (properties and methods), an interface is a group of related properties and methods that describe an object. However, an interface does not provide implementation or initialization for the objects.
Typically, a class defines what an object should look like and act like, and accordingly, it creates and implements a blueprint by initializing the class properties and defining methods. Classes are present throughout all the phases of a code. An interface, on the other hand, is a virtual structure that exists only within the context of TypeScript. The TypeScript compiler uses interfaces exclusively for type-checking.
