JavaScript Level 9000
summary
Explains how V8-level hacks actually change performance: a V8GL prototype proves OpenGL-bound JS can cross‑compile to Android iOS Xbox PS4, and a NodeJS+SDL runtime powers game networking; shows that property insertion order forces Hidden Classes ordering and triggers deoptimizations; demonstrates numeric arrays forcing unboxing to doubles then reboxing when types change; and outlines the GC that combines generational GC (copying + mark‑sweep) with handle scopes so setting references to null yields predictable reclamation.
