Looking as this essentially covered my entire class on networking in college, I figured it was worth sharing.

I hated working with Angular (web dev framework), because it split up all of the code relevant to a page or component into 4 different files. The mental fatigue from switching between files and keeping track of everything just to switch one thing was too much for me. Unsurprisingly, there are people who agree, and in this article, Derek Comartin shows with an ASP .NET example the advantages of using the titular approach.
