check if debug running in the script?

[gmarzloff]

Hi, is there a simple way to check if a script is/isn't being run in debug mode (similar to preprocessor instructions)?

pseudocode:

#ifdebug 
  doThis();
#endif

Sometimes debug output data are expensive to create. We need a way to test the debug pattern to see if it is enabled before trying to log it:

const hexDebug = newDebug('myapp:hexDump')
if(hexDebug.isEnabled())
    hexDebug(b.printDebug())

It's hexDebug.enabled in @jcalfee's example.
