What is prototype chaining in JavaScript?

Can you explain what prototype chaining is in JavaScript?

Sure! Prototype chaining is a mechanism in JavaScript where an object can inherit properties and methods from another object through its prototype.

How does it work in practice?

When you access a property of an object, JavaScript first checks if the property exists on that object. If not, it looks up the prototype chain until it finds the property or reaches the end of the chain.

Can you give me an example?

Absolutely! If you have an object dog that inherits from animal, and animal has a method bark, calling dog.bark() will work because dog can access bark through its prototype.

What are the benefits of using prototype chaining?

Prototype chaining promotes code reuse and helps in organizing code better by allowing objects to share methods and properties.
