What are the best practices in prototypal inheritance?

Prototypal inheritance allows objects to inherit properties and methods from other objects. Best practices include using Object.create for creating new 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 allows you to create a new object with a specified prototype, which helps in maintaining a clear prototype chain and avoids unintended side effects that can occur when modifying the prototype directly.

What are some common pitfalls to avoid?

Common pitfalls include modifying the prototype of built-in objects, creating deep prototype chains, and not understanding the implications of property shadowing.

How can I implement inheritance in my JavaScript code?

You can implement inheritance by creating a constructor function and setting its prototype to an instance of another constructor, or by using ES6 classes which simplify the syntax for inheritance.
