What is Node.js all about? How did it come about? What prompted Ryan Dahl to create Node? What other languages did he try? Who are some of the companies using Node.js, and why? What does Google think about Node.js, given that they maintain the V8 JavaScript engine used by Node? What are the kind of performance gains you can see in Node?
Answers to all those questions and many more are in a lengthy piece on The Register titled “The Node Ahead: JavaScript leaps from browser into future“. It’s a well done article and rather than excerpt it here, I’d encourage you to go take a look at the full piece. Interesting to read about some of the background of which I was not aware. Good stuff!
