He made many points, Javascript not having great tools and IDE's is only one of them.
It's a valid one though, the Javascript IDE's out there aren't very good. However, that's a function of community support, not language quality. Personally, I don't use an IDE for javascript or RoR programming, I just use Textmate.
I use Eclipse for Java programming, and I don't think I would want to program in Java without it. Maybe it says something about the languages themselves that they require an IDE to develop in.
Actually, many people have tried to build refactoring and editing tools for JS and they always hit the same limitations. The language is just not conducive to tooling. Without a great refactoring tool, big projects become difficult.
