Extending Interfaces
Last updated
What is Extending Interfaces?
Extending interfaces in TypeScript allows you to create new interfaces based on existing ones. This means a new interface can inherit all the properties and methods of a parent interface and add its own unique members, promoting code reuse and establishing a clear hierarchy of types. Think of it like inheritance in classes, but for interface definitions.
