That would work, but there is a drawback in this
approach too : what
do we define exactly ? If we define console.log, maybe developers will
expect console.warn to be defined as well, and start using it without
checks. And maybe console.profile, next. The problem is there is no
standard cross-browser API ( - or I could not find it), so it will be
hard to draw the line of what we allow and what we don't.
If we define our own API, then it's clear.
Well, it depends what you really want, but building a specific API does not
help when you want to integrate existing libraries or helps new
contributors. The firebug API has became a de-facto standard for logging and
is starting to be implemented natively in many browsers.
So, if you want to be really light, as suggested at the start of this
thread, just do this:

If you want a full featured solution, go a little bit further but do not
reinvent the wheel:
http://benalman.com/projects/javascript-debug-console-log/
These approaches provides for me the best solution for the lowest price, and
use a well known API that every Javascript developer knows. I completely
disagree that having a specific API is clearer, since you need to learn one
more stuff.
I am almost -1 for building such API.
I am +1 for any of the above evolutive solution.

Why not simply defining console and console.log()
when it is undefined ?
This would avoid the need to think about using a specific wrapper. WDYT ?

I wasn't aware of this. It's clear now.

I'm not sure what are the exact limitations of logging an array-like
object versus a real array. In firebug, a visible difference is that
you can expand the array as a whole (you have that little "+" on the
left and then have all array properties and methods) , whereas with an
array-like object you only see it's individual elements (that you can
expand as well, individually), but can't expand the array.
