What are some real-world applications of prototypal inheritance?

Prototypal inheritance is widely used in JavaScript. For example, in web development, objects can inherit properties and methods from other objects, allowing for code reuse and a more organized structure.

Can you give me a specific example?

Sure! A common example is creating a 'Vehicle' object that has properties like 'wheels' and methods like 'drive'. Then, you can create a 'Car' object that inherits from 'Vehicle', adding specific properties like 'trunkSize'.

How does this improve code efficiency?

It improves efficiency by allowing developers to define shared behavior in a single place, reducing redundancy and making the code easier to maintain.

Are there any downsides to using prototypal inheritance?

Yes, one downside is that it can lead to complex hierarchies that are hard to manage. Additionally, if not used carefully, it can cause unexpected behavior due to shared references.
