I wanted to ask him/her a few questions like

1. What is the difference between backbone.js and node.js
2. Why do you use angular.js when developing responsive sites
3. If you know HTML 4.0, how easy is it to learn HTML 5.0?
4. Do you still have to calibrate for IE as much today as you did before, as most people use Firefox, Safari or Google Chrome.


IF you can pass these on, I'd appreciate it
