macro definition in javascript

Question

Is there a way that I can define a macro similar to C/C++ macros in Javascript?

I want to use this for debug statements: Something like

#ifdef TEST         


        

Answer 1

var de = false; // true when debugging
function bug( msg ){ ... display msg ... }

Usage:

de&&bug( "hello world")

When "de" is false (production mode), the overhead is minimal.
