Main Concepts

Integration-OrientedRhino SpiderMonkey in Java Interaction with Java (APIs and objects) Helma, Persevere, Narwhal*, RingoJS, Sun Phobos...JScript .Net Chakra (C++) Interaction with Windows APIs

Async. Event-basedOne single threadCooperative («one at a time») with async. callbacksnodejs (V8)

Async. Event-based One single thread Cooperative («one at a time») with async. callbacks nodejs (V8)Cons Pros Vulnerable to synchronous Can handle a lot of operations requests Share failure Low memory usage Doesn’t use other cores Uses only one core Hard to debug and maintain

Thread-basedOne thread per contextPreemptive: Parallel code executionAbout all others
