Node.js Feature Livecoding

on YouTube ↗35m

" summary

Rebuilds setTimeout reimplemented in C++ for Node core, wiring V8 bindings to libuv by creating a TimerWrap subclass of libuv handles and requests, exposing start/stop methods, and using async_wrap hooks for lifecycle and diagnostics. Compiles Node (V8 build takes time), iterates through boilerplate and typos until timers fire correctly, and demonstrates via the inspector that a native C++ object retains the JS callback so leaks show up in heap snapshots — implementation works after fixes.
