// the below if statement says if there are none in stock, make the current thing the stock;
// otherwise, find the thing that exists and add the stock to this one
// every class should have one thing that it does; single responsibility principle
// controllers single responsibility is to take things in from the internet and return things to the internet; communication with http stuff
// currently, this class both stores info AND communicates http stuff; something with two jobs means you need to break the thing up;
// common interview question: one of the more common ways that people deal with storing data is with a pattern called the repository pattern;
// some people love it, some hate it; it does perform the job; specifically for managing data and data storage;
// INTERVIEW QUESTIONS
// what's the difference between an abstract class and an interface?
// what's the difference between a value type and a reference type?
// can you describe the repository pattern OR can you describe a pattern that you have used in code?
// Repository pattern is one of the more common in software development
// patterns are more for the person reading the code than for being a software developer
// the DataAccessLayer(DAL, DataAccess, Data) are the same as our data folder in React; this is a division of duty significance
// if we reuse the below if/else, we can move that code to aits own method called AddOrUpdate
