What are abstract classes in TypeScript?

What are abstract classes in TypeScript?

Abstract classes in TypeScript are classes that cannot be instantiated directly and are meant to be subclassed.

Can you give me an example of how to use an abstract class?

Sure! Here's a simple example:

abstract class Animal {
    abstract makeSound(): void;
}

class Dog extends Animal {
    makeSound() {
        console.log('Woof!');
    }
}

const myDog = new Dog();
myDog.makeSound(); // Outputs: Woof!

What happens if I try to instantiate an abstract class?

If you try to instantiate an abstract class, TypeScript will throw an error, as abstract classes are not meant to be instantiated.

Are there any limitations to using abstract classes?

Yes, abstract classes cannot be instantiated, and they can only contain abstract methods or concrete methods.
