Javascript Koans

I've started studing javascript, because in my project one work-mate is using jquery-dataTable + JSON.

So I thought, I must learn this language. One way is throught koans.
I down the needed files from account github. Later I des-compressed the .zip file and opened 'about_asserts.js' in the 'topic' folder.

On the other hand I opened 'jskoans.htm' with the browser, and I started.

It's very simple & very useful.
Happy learning!!!!
