You are making the mistake to equate quantity with quality.

I commend your efforts (even though I still find your code style suboptimal 
at best).

But you do not realize that you are not the first person to try this, that 
function serialization as such and certainly in advance is not a good idea 
(especially writing out function code in HTML without escaping), and that 
both the built-in script consoles and Firebug provide this information in a 
more user-friendly and context-sensitive way:

Just type the expression, e.g. “Math” and click the result, or type, e.g. 
“inspect(Math)” and see the result in the Inspector pane (right-hand side if 
the console is displayed horizontally, on the bottom if vertically).  Also, 
the console (in single-line mode; Firebug also has a very useful editor 
mode) has auto-completion and tab completion.
