The speed race is on: Vert.x and Node.js

Posted on May 16, 2012 by Chad Lung

Vert.x and Node.js are similar in some ways, and different in others. One such difference is that Node.js only allows you to write code in JavaScript whereas Vert.x allows you to code in Java, Groovy, JavaScript, Ruby and eventually as the team expands: Clojure, Scala and Python. So what happens if you could have as good or better performance (a very simple benchmark – check out the comments though!) than Node.js and you can write your code in your preferred language which may or may not be JavaScript?

Starting out with CoffeeScript

Posted on April 16, 2012 by Chad Lung

I went to a Java conference this past weekend and there were several topics of interest. One of the speakers was talking about Underscore and his examples were all done in CoffeeScript. I had previously looked at CoffeeScript and messed around with it but after seeing it in action I decided to give it full second look. If you work with JavaScript in the browser or Nodejs on the server then CoffeeScript will work for you regardless and it makes it easier to work with than just plain JavaScript.
