Devs: What is your favourite Web App Framework?

Web Developers, what is your favorite web framework to use and why?

A web framework is a software framework that is designed to support the development of dynamic websites, web applications, web services and web resources.

A few examples of web frameworks are:
Symfony, Ruby on Rails, Django, Sinatra, Zend, Laravel, CodeIgniter, CakePHP, etc.

I personally favor Ruby on Rails, and my second favorite would have to be Django.
I like these two frameworks because they are simple and easy to develop in, which is a good thing in the real world because it is easier to meet deadlines when working on projects.

 

None. I code by hand.
As of IDE - I use Eclipse......
