The V8 JavaScript engine is an open source JavaScript engine developed by Google in Denmark and shipping with the Google Chrome 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 a bytecode or interpreting it. Further performance increases were achieved by employing optimization techniques such as inline caching. With these features, JavaScript applications running within V8 have an effective speed comparable to a compiled binary.[4]
The garbage collector of V8 is a generational stop-the-world collector.[5]
The V8 assembler is based on the Strongtalk assembler[6].
