How V8 Implements JavaScript Closures

V8 creates JavaScript closures by lazily parsing functions, using a pre‑parser to detect and record outer‑variable references, copying captured values to the heap, then generating bytecode that builds a function context and closure, ensuring efficient execution while avoiding memory‑leak pitfalls.
