The only thing that surprises me here are the loose equality comparisons between object and array; but it's not as though any sane programmer would be doing this. Otherwise almost all the others look fairly intuitive: coercion is applied to satisfy the operator being applied.
It's perhaps more useful to understand all the values that can be coerced to false; and why sometimes it's a really bad idea to use a shortcut if(isSomeValueTruthy) style condition...
edit - actually [] + 1is weird :D
