Factory & Constructor Functions

Factory functions require the 'new' keyword while constructor functions don't
Constructor functions require 'this' while factory functions don't
Factory functions explicitly return objects while constructor functions implicitly create them using 'new'
The key difference is that factory functions are regular functions that explicitly return objects, while constructor functions are meant to be used with the 'new' keyword which implicitly creates and returns an object. Factory functions provide more flexibility in object creation and don't require the 'new' keyword, making them less prone to errors if developers forget to use 'new'.
There is no difference between them
