When it’s not a constructor function or class, it’s called a factory function. es6 classes desugar to constructor functions, so everything that follows about constructor functions also applies to. Discuss private variables and functions concerning factory functions. showcase object inheritance with the help of factory functions. describe what module pattern and iifes are. discuss encapsulation and how the module pattern helps with namespacing. This documentation provides a comprehensive comparison of factory functions and constructor functions in javascript, including their syntax, usage, advantages, disadvantages, and use cases. it also includes practical examples to ensure a deep understanding.

Constructor functions are used to construct or create an object. it is another pattern for creating objects just like the factory functions. it differs from the factory function in its use. Factory functions return objects explicitly and offer better flexibility and encapsulation (closures), while constructor functions use the new keyword and automatically set up prototypal inheritance, sharing methods across instances.
