What is method overriding in ES6 classes?

Method overriding in ES6 classes allows a subclass to provide a specific implementation of a method that is already defined in its parent class.

Can you give me an example of method overriding?

Sure! If you have a class Animal with a method speak(), a subclass Dog can override speak() to provide a dog-specific implementation.

How do I implement method overriding in my code?

You simply define the method in the subclass with the same name as in the parent class. Here's a quick example:

class Animal {
  speak() {
    console.log('Animal speaks');
  }
}

class Dog extends Animal {
  speak() {
    console.log('Dog barks');
  }
}

In this case, calling new Dog().speak() will output 'Dog barks'.

Are there any limitations to method overriding?

Yes, method overriding can lead to issues like the diamond problem in multiple inheritance scenarios, but ES6 classes use prototypal inheritance to mitigate this.
