How do I create a constructor in JavaScript?

Can you explain how to create a constructor in JavaScript?

Sure! In JavaScript, a constructor is a special function used to create and initialize objects. You define it using the 'function' keyword and typically capitalize the first letter of the function name.

What does the 'new' keyword do when using a constructor?

The 'new' keyword creates a new object, sets the prototype of the new object to the constructor's prototype, and calls the constructor function with the new object as its context.

Can you give me an example of a simple constructor?

Of course! Here's a simple example:

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

const john = new Person('John', 30);
console.log(john); // Person { name: 'John', age: 30 }
