What is the difference between constructors and factory functions in JavaScript?

Can you explain the difference between constructors and factory functions in JavaScript?

Sure! Constructors are special functions used to create objects using the 'new' keyword, while factory functions return objects without using 'new'.

What are the advantages of using factory functions over constructors?

Factory functions can provide more flexibility, allow for private variables, and avoid issues with 'this' context that can occur in constructors.

Can you give me an example of each?

Of course! A constructor example: function Person(name) { this.name = name; }. A factory function example: function createPerson(name) { return { name }; }.

When should I use one over the other?

Use constructors when you need to create multiple instances with shared methods, and factory functions when you need more control over object creation.
