Talk: Non-alphanumeric code in JavaScript and PHP

Slides:

Understanding how to create non-alpha code leads to a deeper understanding on how the particular language works.

Gareth shall discuss the history of non-alpha JavaScript, the challenges and creativity behind it.

How can you decode:

$=~[];$={___:++$,$$$$:(![]+"")[$],__$:++$,$_$_:(![]+"")[$],_$_:++$,$_$$:({}+"")[$],$$_$:($[$]+"")
[$],_$$:++$,$$$_:(!""+"")[$],$__:++$,$_$:++$,$$__:({}+"")[$],$$_:++$,$$$:++$,$___:++$,$__$:++$};
$.$_=($.$_=$+"")[$.$_$]+($._$=$.$_[$.__$])+($.$$=($.$+"")[$.__$])+((!$)+"")[$._$$]+($.__=$.$_[$.$$_])
+($.$=(!""+"")[$.__$])+($._=(!""+"")[$._$_])+$.$_[$.$_$]+$.__+$._$+$.$;$.$$=$.$+(!""+"")[$._$$]+
$.__+$._+$.$+$.$$;$.$=($.___)[$.$_][$.$_];$.$($.$($.$$+"\""+$.$_$_+(![]+"")[$._$_]+$.$$$_+"\\"+
$.__$+$.$$_+$._$_+$.__+"("+$.__$+")"+"\"")())(); 

Gareth will explain.

Gareth shall also cover how to create this in PHP and what techniques are involved.
