Cross-platform if you want
Node.js is cross-platform meaning it works on Windows, OSX and Linux. A large number of the Node.js community write Node.js on OSX and then deploy to Linux servers. Because OSX and Linux are based on UNIX this tends to just work. Windows support is a first-class citizen in Node.js and if you learn to use Node.js in the right way you can make sure that you can welcome your Windows friends to your code party.
