The Google V8 JavaScript Engine is an open source JavaScript engine developed by Google. It ships with the Google Chrome web browser.[2] Lars Bak is the head programmer.[3]
V8 increases performance by compiling JavaScript to native machine code before executing it, rather than to execute bytecode or interpreting it. Further performance increases are achieved by employing optimization techniques such as inline caching.
