Can interfaces extend classes in TypeScript?
In TypeScript, interfaces cannot extend classes directly. However, they can extend other interfaces.
What does it mean for an interface to extend another interface?
When an interface extends another interface, it inherits the properties and methods of the parent interface, allowing for more complex structures.
Can you give me an example of this?
Sure! If you have an interface Animal
and another interface Dog
that extends Animal
, Dog
will have all properties of Animal
plus any additional ones defined in Dog
.
What about classes? Can they implement interfaces?
Yes, classes can implement interfaces. This means the class must define all the properties and methods specified in the interface.
