V8 is Google’s open source JavaScript engine.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 implements ECMAScript as specified in ECMA-262, 5th edition, and runs on Windows (XP or newer), Mac OS X (10.5 or newer), and Linux systems that use IA-32 (SSE2 required), x64, ARM (ARMv6 + VFP2 required) or MIPS processors.

V8 can run standalone, or can be embedded into any C++ application.
