Chrome V8 engine

Abstract

• V8 is an open sourced Javascript engine for web browsers.
• V8 compiles JavaScript directly to native machine code before executing it.
• The compiled code is additionally optimized (and re-optimized) dynamically at runtime (Inlining)
• Garbage collection is done more efficiently. Instead of doing the freeze-it-all mark-and-sweep it does garbage collection incrementally now. And the sweep phase is done by separate threads.
