The browser is rapidly becoming the new operating system. JS finally becomes a first-class citizen, not just a lowly pop-up vector. Now with WebGL and WebCL, it will be unstoppable.
Lua's an absolute travesty. It's a shame they decided to use it as the implementation, because it's not like capable JS implementations don't exist or anything.
At least they didn't expose it at an API level. That's one redeeming feature at least.
Really? I don't see anything particularly wrong with Javascript... I mean, sure it's no PHP, but compared to travesties like Lua (1-based, seriously? What year is it again?) and bloated, convoluted semantic messes like Python and Ruby... well there aren't many choices left!
Google, Mozilla, Microsoft, and Opera (and obviously Apple) haven't exactly been jumping at the opportunity to deprecate Javascript in or out of the web. I mean hell, now we have technologies like Node and asm.js that make Javascript the fastest dynamic language in existence! People are even using it in embedded hardware now! So it can't be nearly as bad as people say.
This is pretty sad considering the immense capabilities of JS.
