How can I create objects in JavaScript using constructors?

How can I create objects in JavaScript using constructors?

You can create objects using constructor functions by defining a function and using the 'new' keyword. For example:

function Person(name, age) {
    this.name = name;
    this.age = age;
}

const john = new Person('John', 30);

What are the benefits of using constructors over object literals?

Constructors allow for creating multiple instances of an object with the same structure, promoting code reusability and organization.

Can I use ES6 classes instead of constructors?

Yes, ES6 classes provide a more modern syntax for creating objects. Here's an example:

class Person {
    constructor(name, age) {
        this.name = name;
        this.age = age;
    }
}

const jane = new Person('Jane', 25);

What about inheritance in JavaScript?

Inheritance can be achieved using prototypes or the extends keyword in ES6 classes. For example:

class Employee extends Person {
    constructor(name, age, position) {
        super(name, age);
        this.position = position;
    }
}
