How do I inherit using constructors in JavaScript?

In JavaScript, you can use constructor functions along with the prototype chain to achieve inheritance. Would you like an example?

Yes, please provide an example.

Sure! Here's a simple example:

function Animal(name) {
    this.name = name;
}

Animal.prototype.speak = function() {
    console.log(`${this.name} makes a noise.`);
};

function Dog(name) {
    Animal.call(this, name); // Call the parent constructor
}

Dog.prototype = Object.create(Animal.prototype);
Dog.prototype.constructor = Dog;

const dog = new Dog('Rex');

dog.speak(); // Rex makes a noise.

What does Object.create do in this context?

Object.create(Animal.prototype) sets up the prototype chain so that instances of Dog inherit from Animal. This allows Dog to access methods defined on Animal.
