The really interesting language in that comparison is LuaJIT. It is faster and more concise than Javascript. It's sad that a mature, small, concise language like Lua doesn't have more traction outside niches.
Furthermore, they are not really trying to promote the language beyond its current niches.
That said, there are good third party libraries and frameworks, and a Rubygems-like system called Lua Rocks.
The fact that Javascript is an in important feature in software that everyone runs is a whole different kind of advantage.
