if [[ $Something ]] – in what situations does this work?

I tried this with the $? variable, but failed. Seems like [[ $? ]] is
always true no matter the value of $?. [[ $? == 0 ]] seems to work,
though.

I thought that ”if [[ $? ]]” means ”if $? is True”. What is True
anyway? 0? 1? Anything but 0?

I am not sure what I am asking for here, but any kind of input in the
subject is welcome. Thanks.


Kind regards
