The V8 JavaScript Engine is an open source JavaScript engine developed by Google. It ships with the Google Chrome web browser.[4] As of 2012, the head programmer is Lars Bak.[5]
V8 increases performance by compiling JavaScript to native machine code (x86,[2] ARM,[2] or MIPS[3] CPUs), before executing it, versus executing bytecode or interpreting it. Further performance increases are achieved by employing optimization methods such as inline caching.
Details
The garbage collector of V8 is a generational incremental collector.[6] The V8 assembler is based on the Strongtalk assembler.[7] On 7 December 2010, a new compiling infrastructure named Crankshaft was released, with speed improvements.[8]
MIPS port
A port to little endian MIPS was released with v8 version 3.7[3].[who?]
Usage
V8 is intended to be used both in a browser (notably in Chrome and Chromium browsers) and as a standalone high performance engine that can be integrated into independent projects, for example server-side JavaScript in Node.js.[9]
