Why? Mozilla loved V8 and WebKit – Internet Explorer’s Chakra, not so much.
Spidermonkey is old – it was created in 1996.
V8 has a nice C++ API.
Eich is going over some of the features already approved for Harmony. You can find his previous blog post on the subject here Various parts of CoffeeScript may or may not be going into Harmoney. You can find out more about this at in Eich’s JSConf talk.
Q: Where will Spidermonkey beat V8 for Node?
A: Spidermonkey is not really in competiton with V8 for Node, but it depends on the workload.
Q: Ryan Dahl asked about debugging.
A: They’re working on debuggers.
Q: Did you have to compromise anything because you were trying to shoehorn the project into V8’s API?
A: There have problems that lead to re-writing some elements.
