Okay, this looks really very interesting. Although DefiantJS indeed appears to be a new and promising framework for use in JSON manipulations, what I find _especially_ catches my attention is the XSLT implementation and what I can do with XML. XPATH rocks! When you combine to possibilities for advanced JSON support with XSLT you have a nice solid set of features for creating data client applications for browsers and more. This is actually something I have been looking for for quite a while! I'm anxious to dig deeper into this. Many thanks Hakan ;)
