I was answering about how they work together. Javascript is very backend independent. PHP's json_encode is a huge timesaver, but in essence ajax calls could go to small html snippet files and it would work.
I wouldn't call it easy though. I'm working on a YUI app right now, and yes it can be a huge pain. Javascript is one of the worst languages to debug, even with tools like firebug.
On the other hand it's also one of the greatest language to work with. One file and you're good to go - no compiling, every computer has an interpreter (browser). I also find it quite amusing. Animations aren't everything, but they sure are fun.
The question was about CodeIgniter + Javascript and my answer is - it'll work no problem.
Making it degrade is a different story.
