I could use some suggestions as well. I'm using VIM and doing most of the AJAX work manually (with JQuery). js is a pain though -- anyone know a better way to get this stuff done?
I use VIM too. What exactly do you find is a pain?
vim here with jquery too. working phenomenally well for me, though I understand there's no kind of js debugging built into vim. The matching braces highlight function is my debugging tool.
