I'm not much of a PHP coder, so I tend to watch these flamewars from a distance on the sidelines.<p>However, I've never really understood why people criticize or mock Facebook for pouring so many resources into PHP. For building cross-compilers, toolchains, and syntactic extensions on top of a language that is seen as a fundamentally weak foundation.<p>I mean, I DO understand all of those criticisms. I just don't get how the same people can then turn around and use CoffeeScript, TypeScript, Dart, and even Node.js on the <i></i>server-side<i></i>. Compared to a JavaScript foundation, PHP is bedrock!
