What is polymorphism in JavaScript?
Polymorphism in JavaScript allows objects to be treated as instances of their parent class, enabling method overriding.
Can you give me an example of polymorphism in action?
Sure! Consider a base class Animal
with a method speak()
. Subclasses like Dog
and Cat
can override speak()
to provide their own implementations.
How does this differ from inheritance?
Inheritance is about creating a new class based on an existing class, while polymorphism allows methods to be used interchangeably across different classes.
Are there any real-world applications of polymorphism?
Yes! Polymorphism is widely used in frameworks and libraries, allowing for flexible and reusable code, especially in event handling.
