	// I think Ben's solution looks good although I probably wouldn't have used promises because
	// I sometimes think the interface to them is confusing and you are locked into their interpretation not your own,
	// If I did use them I would try and bury them behind my own interface. There are always going to be million
	// different ways to do the same thing in angular so I try and model the problem in terms of OO design as opposed to
	// language specific or angular specific, and of course making something easy to test is always my highest priorities.
	// Coupling tests to promises is hard and they are difficult to read. So I would use promises in the background not in
	// the foreground design.

	// I have identified that we have 3 entities in this solution.

peterheard01 / structure_coupling.js

Last active January 3, 2022 15:03

An example of coupling and decoupling in Javascript

	//this type of coupling happens when you expose the internals object A to object B
	//in this example we are accessing a method and assigning a property.
	//this type of coupling happens when one module asks a question of another module
	//if Person changes how it represents 'hasHobby' it breaks the coupled version in
	//2 places
	//by using a 3rd object to hold that information we only break the code in 1
	//place if we ever change how the Person represents hwo they have a hobby

	//coupled
	function main(){
