1) As mentioned in the blog post, we have taken the time to actually build in ObjJ support into WebKit's debugger and profiler. I would classify this as one of the best debugging and profiling experiences for JS out there (not that there is much competition).

We ship a compiler/obfuscator/compressor that will spit out the same illegible code that you would get if you were just using JavaScript with a compressor. It will also concat all the files together to dramatically improve load times.
