    copied!<p>I am new to this kind of stuff, but lately I've been hearing a lot about how good <a href="http://en.wikipedia.org/wiki/Node.js" rel="nofollow noreferrer">Node.js</a> is. Considering how much I love working with jQuery and JavaScript in general, I can't help but wonder how to decide when to use Node.js. The web application I have in mind is something like <a href="https://en.wikipedia.org/wiki/Bitly" rel="nofollow noreferrer">Bitly</a> - takes some content, archives it. </p> <p>From all the homework I have been doing in the last few days, I obtained the following information. Node.js </p> <ul> <li>is a command-line tool that can be run as a regular web server and lets one run JavaScript programs</li> <li>utilizes the great <a href="http://en.wikipedia.org/wiki/V8_%28JavaScript_engine%29" rel="nofollow noreferrer">V8 JavaScript engine</a></li> <li>is very good when you need to do several things at the same time</li> <li>is event-based so all the wonderful <a href="http://en.wikipedia.org/wiki/Ajax_%28programming%29" rel="nofollow noreferrer">Ajax</a>-like stuff can be done on the server side</li> <li>lets us share code between the browser and the backend</li> <li>lets us talk with MySQL</li> </ul> <p>Some of the sources that I have come across are:</p> <ul> <li><a href="http://www.stoimen.com/blog/2010/11/16/diving-into-node-js-introduction-and-installation/" rel="nofollow noreferrer">Diving into Node.js – Introduction and Installation</a></li> <li><a href="http://debuggable.com/posts/understanding-node-js:4bd98440-45e4-4a9a-8ef7-0f7ecbdd56cb" rel="nofollow noreferrer">Understanding NodeJS</a></li> <li><a href="http://blog.osbutler.com/categories/node-by-example/?page=3" rel="nofollow noreferrer">Node by Example</a> (<a href="http://archive.is/exhaR" rel="nofollow noreferrer">Archive.is</a>)</li> <li><a href="http://dailyjs.com/2010/11/01/node-tutorial/" rel="nofollow noreferrer">Let’s Make a Web App: NodePad</a></li> </ul> <p>Considering that Node.js can be run almost out-of-the-box on <a href="http://en.wikipedia.org/wiki/Amazon_Elastic_Compute_Cloud" rel="nofollow noreferrer">Amazon's EC2</a> instances, I am trying to understand what type of problems require Node.js as opposed to any of the mighty kings out there like <a href="http://en.wikipedia.org/wiki/PHP" rel="nofollow noreferrer">PHP</a>, <a href="http://en.wikipedia.org/wiki/Python_%28programming_language%29" rel="nofollow noreferrer">Python</a> and <a href="http://en.wikipedia.org/wiki/Ruby_%28programming_language%29" rel="nofollow noreferrer">Ruby</a>. I understand that it really depends on the expertise one has on a language, but my question falls more into the general category of: When to use a particular framework and what type of problems is it particularly suited for?</p>
