I've been meaning to do a roll-up of top JavaScript, CSS & HTML development tools that I use or have been recommended to me and after having lunch with my bud Brian Wilpon today, I realized I just needed to do it. He asked me what some of the newer tools are and I think this is the best way to help him (and the community in general). It's definitely not an all-inclusive list so if you see some that you feel I should add or remove, let me know in the comments.

Here they are by category:
