Finally yesterday,which was co-incidentally my birthday, i started learning Node.js .
Prior to learning this, I had a modest understanding of HTML, CSS and Object Oriented Javascript. I must say, i was pleasantly surprised with the simplicity in creating Applications with Node.js and the simplicity in adding new modules using NPM.
The tutorial that started me off is - https://tutsplus.com/lesson/hello-node-js/
This one is a premium tut from http://net.tutsplus.com/ , and it is really worth it.
