What is Interface?
An interface in TypeScript is a way to define a contract for the shape of an object. It names a set of properties and their types that an object must have. Think of it as a blueprint that specifies the properties (and optionally, methods) that an object should possess, allowing you to ensure that different parts of your code work together smoothly by enforcing a consistent structure.
