What are factory functions in JavaScript?

Can you explain what factory functions are in JavaScript?

Sure! Factory functions are functions that return objects. They allow you to create multiple instances of an object with similar properties and methods.

How do they differ from constructor functions?

The main difference is that factory functions do not use the new keyword and do not require the creation of a prototype chain. They simply return an object.

Can you give me an example of a factory function?

Absolutely! Here's a simple example:

function createCar(make, model) {
    return {
        make: make,
        model: model,
        drive() {
            console.log(`Driving a ${this.make} ${this.model}`);
        }
    };
}
const myCar = createCar('Toyota', 'Corolla');
myCar.drive(); // Output: Driving a Toyota Corolla
