[@Captain Jordan]: :btw GraphicsMagick and ImageMagick are language-agnostic command-line utilities (C libraries). Pretty much every language that runs on the server including Javascript (via Node.js runtime) has wrappers for it. Or you can just execute commands on the shell from the server-side language. For example, in Javascript: [code]conosle.log(yield shell.exec('ls'))[/code] => [code]'file1.txt\nfile2.txt\nflower.png'[/code].

I think you may be looking at server-side Javascript (not much different than Python, Ruby, Scheme, ...) through the lens of client-side Javascript running in the browser. The latter is obviously very limited.

The main drawback of Javascript is that it's single-threaded, but same with Python and Ruby and PHP -- effectively -- due to their global interpreter lock (GIL). You simply shell out CPU-bound operations to other processes. In this case, ImageMagick/GraphicsMagick, which may spin up a dozen threads to process an image before handing the result back to the Node.js process.

Fair enough.
