Node.js feature Livecoding

on YouTube ↗33m

" summary

Live coding shows setTimeout implemented in C++ by wiring V8 to libuv with handle‑wrap classes, UV_timer_init/start callbacks and a JS-facing constructor; code runs under --expose-internals, exercises libuv handles and requests, and requires calling close to avoid leaks. Async hooks appear via async tracking visible events (init, before, after, destroy). Inspector heap snapshots confirm native timer instances and report 64-byte native objects, the implementation compiles and the demos execute successfully.
