Using function's return value in if statement

Question

Hopefully a quick question here.

Can you use a function\'s returned value in a if statement? I.e.

  return false;

}

if(q

You can simply use

if(queryThis('foo')) { doThat(); }

function queryThis(parameter) {
    // some code
    return true;
}
