In this case, maybe not a big deal. Say, however, you'd like to take an app that would normally consume 30% of your CPU and convert it to JS: Then it would require 105% of your CPU and you'll be screwed. (It's actually worse than that: I have a dual core processor, so a JS app couldn't use more than 50%, An app that would normally consume 15% would not work in JS)
I'm the first to admit that premature optimization is the root of all evil, Javascript has severe performance and functionality limitations. The language itself is arguably worse than languages that don't. This isn't like c#/java vs C. Javascript isn't easier or faster to develop in for most situations.
