Pro.Prototypes Workshop
summary
A hands-on workshop that explores JavaScript prototype mechanics using live code in the browser console and Node with Chrome inspect. It demonstrates extremely deep prototype chains (up to 1000 levels) to reveal performance limits, constructs mixed class/function chains to emulate super calls, and shows replacing the chain tail with a proxy-backed prototype end. Examples include a TypeScript library providing a strict-typing decorator that throws on type mismatches and an async lifecycle decorator that delays inheritance; all demos and source code are on GitHub and most run live despite occasional debugger issues.
