Anybody has experience with the upcoming IE9 Chakra engine? I am currently considering whether to incorporate the Microsoft's JScript engine through the Window Script Interface or using one of those open source javascript engines (tracemonkey/v8 etc).
The JScript engine is a bit too slow and Chakra looks promising. But I am not sure if it will be accessible the same way as before since Active Scripting should be deprecated.
Anybody get some idea?
