TypeScript Interfaces Extending Interface
Example
Suppose we have an interface:
interface IPerson {
name: string;
age: number;
breath(): void;
}
And we want to create more specific interface that has the same properties of the person, we can do it using the extends keyword:
interface IManager extends IPerson {
managerId: number;
managePeople(people: IPerson[]): void;
}
In addition it is possible to extend multiple interfaces.
