foo(bar,fly);

Marginally useful console.log shorthand.

Ad-hoc logging:

foo('bar');
// [13:03:20] bar

var bar = 'fly';
foo(bar);
// [13:03:20] fly

var bar = ['foo','bar','fly'];
foo(bar);
// [13:03:20] object:
0 foo
1 bar
2 fly

var bar = { foo: 'foo', bar: 'bar', fly: 'fly'};
foo(bar);
// [13:03:20] object:
bar bar
fly fly
foo foo

Optional coding standard for enabling emergency debug mode:

function whatever() {
  foo('whatever',1);
  ...
}
// (no log)

var paranoid = true;
function whatever() {
  foo('whatever',1);
  ...
}
// [13:03:20] whatever
