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.

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 ?

What's the point of Array.prototype.slice.call(arguments) ?
Apparently it's a trick to transform the "arguments" array-like object
into an array. See hhttps://
developer.mozilla.org/en/JavaScript/Reference/Functions_and_function_scope/…
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.
Thanks,
