AngularJS is awesome! Yeah, it is, even after so many competitors it still did not lose its value and manages to be on top of others. So we all love it and wonder how it can be so cool, same goes for me. The one thing I really inspired with is Angular's
watch function which automatically gets called when object bind with $scope got changed. So it's inevitable for me to learn how watch function works and by learning this I come up with the idea that how I can create my own simple watch function with simple JavaScript.
