Discussion on: JavaScript Design Patterns - Factory Pattern

Hello Kristijan.
Want to add some things here. You are very much setting a context of this pattern in class based environment. Also implementation use Class with one method. The reality is - factory is just a function, and it simplify data structure creation.

const makeVehicle = (name, type) => ({name, type});
const makeCar = (name) => makeVehicle(name, 'car');
const makeTruck = (name) => makeVehicle(name, 'truck');

// end even more concise by point free
const makeVehicle = (type) => (name) => ({name, type});
const makeCar = makeVehicle('car');
const makeTruck = makeVehicle('truck');

Let me repeat again, factory is just a function which allows in centralized way to create structures in proper shape, thanks to that we are sure that the created object has proper structure and somebody did not missed some fields or done some typo (very often in JS world)

Its simple thing. There is no reason to complicate it.
