You may have heard about Node.JS and wondered what the heck it was. Well, it's pretty cool. It's built on Google's V8 Javascript engine. It's used for quickly writing fast, scalable network applications. Node.JS is geared towards creating real-time interactivity on the web. If you've wanted to program chat application, a stock ticker, or anything that required instant data updating pushed out to thousands of users, Node.JS is what you've been looking for. I picked up the book "Jump Start Node.JS" from SitePoint. I've mentioned SitePoint before, I really do love their books. You can also check out the Node.JS group at http://nodejs.org
