When I started using Ruby and Rails in 2004 I immediately knew that Rails was going to be huge. At that time I was working mostly with Java.

Ruby and Rails brought so much joy to my programming world that it was kind of a revolution in my programming passion. This revolution is still going on, I'm still happy with Ruby and Rails even if I sometimes criticize some aspects of it.

There is however a new thing that triggered a new (r)evolution in my programming world.

This thing is called CoffeeScript.

I know that Coffee is only a "patch" to JavaScript, but for me this slight change is huge. The syntax is the prettiest combination of Ruby and Python that I have ever seen.

The code written in Coffee is so pretty that it almost allows you to think at new levels of abstraction. Yes, it's that huge to me.

I never especially liked working with JavaScript on the front-end. I preferred to focus on Ruby backends. Now it's harder to me to switch from frontend code to server Ruby code.

I still love Ruby, but CoffeeScript is officially becoming my new passion, equal to Ruby. If you haven't given it a try, then you should. It's so worth it.
