An example of an AI chatbot conversation about abstract vs concrete classes in JavaScript.
What is the difference between abstract and concrete classes in JavaScript?
In JavaScript, abstract classes cannot be instantiated directly and are meant to be subclassed, while concrete classes can be instantiated.
Can you give me an example of an abstract class?
Sure! An abstract class in JavaScript can be created using a class with a method that throws an error if not overridden.
How do I create a concrete class that extends an abstract class?
You can create a concrete class by extending the abstract class and implementing its abstract methods.
What happens if I don't implement the abstract methods in the concrete class?
If you don't implement the abstract methods, the concrete class will also be considered abstract and cannot be instantiated.
