prototype gone wild…
Perfection Kills
Exploring Javascript by example
About
I am Juriy Zaytsev, otherwise known as "kangax" — front end web developer based in New York. Most of my work involves exploring and taming various aspects of Javascript. I'm an ex- Prototype.js core developer. This blog is for sharing and ranting about my findings.
