What are the best practices for using prototypal inheritance in JavaScript?

Prototypal inheritance allows objects to inherit properties and methods from other objects. Best practices include using Object.create() for creating objects, keeping the prototype chain clean, and avoiding modifications to the prototype of built-in objects.

Can you explain why using Object.create() is preferred?

Using Object.create() is preferred because it allows you to create a new object with a specified prototype, which helps in maintaining a clear prototype chain and avoids issues related to constructor functions.

What are some common pitfalls to avoid?

Common pitfalls include modifying the prototype of built-in objects, which can lead to unexpected behavior, and not understanding the implications of the 'this' keyword in methods.

How can I ensure my prototype chain is clean?

To ensure a clean prototype chain, avoid deep inheritance hierarchies, use composition over inheritance when possible, and regularly review your prototype structure.
