I'd say Netbeans is a comparable free option. VS isn't generally known for its JavaScript capabilities.

The problem I see with NetBeans is that it consumes a lot of resources. There are better & lighter options.

While I don't have Webstorm, IntelliJ IDEA Community Edition consumes 250,000 kb with an empty project open while Netbeans consumes a bit under 400,000 kb, both without any sort of tweaking -- that's not that great of a difference to me. Vim, for instance, would be light.
