What are advanced constructors in JavaScript?

Advanced constructors in JavaScript are functions that create objects with specific properties and methods, often using the 'new' keyword.

Can you give me an example of an advanced constructor?

Sure! Here's an example:

function Car(make, model) {
    this.make = make;
    this.model = model;
    this.displayInfo = function() {
        return `Car: ${this.make} ${this.model}`;
    };
}

const myCar = new Car('Toyota', 'Corolla');
console.log(myCar.displayInfo()); // Car: Toyota Corolla

What is the difference between a constructor and a factory function?

A constructor function is called with the 'new' keyword and creates an instance of an object, while a factory function returns an object without using 'new'.

When should I use advanced constructors?

Use advanced constructors when you need to create multiple instances of an object with shared properties and methods, promoting code reuse.
