Some explanations:<p>1. Yes, I'm aware of Microjungle but still don't get why does it weigh twice bigger and above. 323 bytes of XT.js is NOT gzipped size.<p>2. This library is VERY strict to the syntax. Any mistake - flow ruined.<p>3. You know how to deal with DocumentFragments, right?<p>4. No serverside planned, sorry.<p>5. Yes, it's already used in production.
