title: Obfuscated code without function calls
body: <p>I've seen examples of code that uses only operators and <code>""</code> to perform complex string operations. Basically, the idea was that something like <code>((+"+")+"")[+""]</code> gives you a letter <code>N</code>, etc. I forgot where I found it,  and I'm having no luck finding proper google keywords. Does anyone have a link at hand?</p>
