How can I extend interfaces in TypeScript?

In TypeScript, you can extend interfaces using the extends keyword. For example, interface A {} and interface B extends A {}.

Can you give me an example of extending multiple interfaces?

Sure! You can extend multiple interfaces like this: interface C extends A, B {}. This way, interface C will inherit properties from both A and B.

What happens if there are conflicting properties in the extended interfaces?

If there are conflicting properties, TypeScript will throw an error. You need to resolve the conflict by defining the property in the extending interface.

Is it possible to extend an interface with a class?

Yes, a class can implement an interface, but it cannot extend it. However, you can create a new interface that extends the original interface and then implement that in your class.
