Why Angular JS

Question

What is angular JS doing so specific that we are catching it fast?  

Knockout, TypeScript or even basic jquery could help you getting there.

 

Do we any practical example where real time app is designed using Angular JS?  

 

It is simple client framework.  What could we achieve using Angular if supportive browser is not there?  

 

Is it making web client dev easy and providing functionality to debug it faster? Could we add-in any Ajax framework into Angular? 

 

Please share some more details. 

 

Thanks,
