I'm just curious why Node.js was named that. I searched their site and their FAQ and there was nothing that helped me understand why it was named Node.js.
The official name is actually Node. Originally it was designed for use as a web application, but the author realized it could be used for more general purposes and renamed it to node.
Here is a quote from the author that may help explain the name:
Node is a single-threaded, single-process system which enforces shared-nothing design with OS process boundaries. It has rather good libraries for networking. I believe this to be a basis for designing very large distributed programs. The “nodes” need to be organized: given a communication protocol, told how to connect to each other. In the next couple months we are working on libraries for Node that allow these networks.
