JSFiddle

Today I was looking for an online Web Editor to try some Javascript things, after trying a couple not good pages, i finally found out one that satisfy my tests.. JSFiddle.



Now it is in the alpha version but it works pretty good, i was not just able to try entires codes of javascript but also html, CSS3. I could even add frameworks for the final preview.
It has even integration with social networks and user account module.

I will keep trying this development tool in the next days to see if its that good as it seems.
