On what planet is Javascript anywhere near to the "lowest level"?

Earth.  People are building x86 emulators and Linux kernels written in JavaScript.  As Scott Hanselman has repeatedly pointed out in the last year or so, JavaScript is the assembly language of the web. 

If you haven't watched his presentation from build, you owe it yourself to do so.  Probably the best level-setting presentation about how things actually are in the 2010s I've seen.
