I think you were referring to the JavaScript syntax when you said JavaScript is full of flaws, because IMHO the language itself - except the syntax component - is actually very good. Someone on Quora said[1] it very well:
JavaScript is a wonderful language, deep down: It's Lisp-y, yet imperative. Its lack of support for threads has turned out to be a strength on the server side. And recent implementations have made it very fast.
People favoring node.js and compile-to-JS languages like Iced CoffeeScript to other server-side languages supports the fact that JavaScript itself is actually quite decent. At the end of the day, a language too broken could not easily be fixed with any thin compile-to-* effort, and most of the compile-to-JS efforts (with the notable exception of emscripten, whose goal is not to fix JavaScript) are quite quite thin.
