Can you explain how inheritance works in JavaScript?
Sure! In JavaScript, inheritance is primarily achieved through prototypes. Each object has a prototype, and it can inherit properties and methods from that prototype.
What is the difference between prototypal inheritance and classical inheritance?
Prototypal inheritance is based on prototypes, where objects inherit directly from other objects. Classical inheritance, on the other hand, is based on classes and is more common in languages like Java.
How do I create a subclass in JavaScript?
You can create a subclass using the class
syntax with the extends
keyword. For example, class Dog extends Animal {}
allows Dog to inherit from Animal.
Can you give me an example of using Object.create
for inheritance?
Absolutely! You can create a new object that inherits from another object using Object.create()
. For example: const dog = Object.create(animal);
makes dog
inherit from animal
.
