I was just trying http://plnkr.co and i found the same really interesting. I was just trying my hands with few angular basics and found the tool really cool, hence thought to share the same.
Below example is just a databinding using ng-controller.
Below example just explains how to use $http service. Here, i have just used my git profile to make an http call.
Below is the same example what we have seen above but with a little tweak; this time with ng-module.
However, this is not a angular series just a refresher. Angular series is already shared.
