" summary

React Native shows a concrete architecture: real JavaScript runs on JSCore and V8, UI is native components wired over an asynchronous bridge, and the layout engine outputs top/left/width/height after a flexbox pass that was reimplemented in about two weeks and then ported to C and Java. Live edit cycle is dramatic—hot reload under one second versus ~30 seconds for Xcode rebuilds. Errors surface in a visible “red screen of death,” and a minimal codebase is released to a private GitHub repo at 6 PM.
