What is a Factory Function?

This article introduces JavaScript factory functions, which are functions that return new objects. It covers basic usage, demonstrates how they can replace classes by using closures for private methods/state (avoiding the 'this' keyword), and provides practical examples like creating a queue data structure. It also mentions real-world applications, such as using factories in a data structures course and for package upgrades.
