Object-Oriented Programming for Web Developers: Lessons From an Old Flash Game
Most web developers I’ve worked with can build a React component, wire up an API route, and deploy to Vercel. What many of them can’t do is tell you what a class hierarchy is for, when to use inheritance versus composition, or why separating data from behaviour matters. This isn’t their fault.
