What is prototype chaining in JavaScript?

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

Can you give me an example of prototype chaining?

Sure! If you have an object animal with a method speak, and another object dog that inherits from animal, calling dog.speak() will access the speak method from animal.

How does the __proto__ property work in this context?

The __proto__ property allows you to access the prototype of an object. For example, dog.__proto__ would refer to the animal object, enabling access to its properties and methods.

What are the benefits of using prototype chaining?

Prototype chaining promotes code reuse and organization, allowing for a cleaner and more efficient way to manage shared properties and methods.
