V8 engine, JS Code Interpretation, and Execution
summary
Walks through how V8 turns JS source into running machine code with concrete mechanisms: hidden class transitions that explain property access speed, inline caching patterns that avoid repeated lookups, a baseline and optimizing compiler pipeline that produces faster code, and a Node/V8 demo measuring big wins (claims up to 200x in specific microbenchmarks) plus what actually got implemented and when the optimized case falls back to slower interpretation.
