What is the prototype chain in JavaScript?

Can you explain what the prototype chain is in JavaScript?

Sure! The prototype chain is a mechanism in JavaScript that allows objects to inherit properties and methods from other objects.

How does inheritance work through the prototype chain?

Inheritance works by linking objects through their prototypes. When you access a property, JavaScript looks at the object itself first, then its prototype, and so on up the chain.

Can you give me an example of the prototype chain in action?

Absolutely! For instance, if you have an object dog that inherits from animal, and animal has a method bark, dog can use bark through the prototype chain.

What happens if a property is not found in the object or its prototype?

If a property is not found, JavaScript will return undefined. If you try to access a method that doesn't exist, it will throw a TypeError.
