How do I use Object.create in JavaScript?

Object.create is a method that creates a new object with the specified prototype object and properties. You can use it like this: const newObj = Object.create(protoObj); where protoObj is the object you want to inherit from.

Can you give me an example of how to use it?

Sure! Here's an example:

const animal = { eats: true };
const rabbit = Object.create(animal);
console.log(rabbit.eats); // true

In this case, rabbit inherits the eats property from animal.

What if I want to add properties to the new object?

You can add properties by passing a second argument to Object.create. For example:

const rabbit = Object.create(animal, { jumps: { value: true } });
console.log(rabbit.jumps); // true

This adds a jumps property to the rabbit object.

Is Object.create better than using a constructor function?

It depends on your use case. Object.create is great for prototypal inheritance, while constructor functions are useful for creating multiple instances of an object with shared properties.
