more , more find myself writing structure of if statements looks this: if(something) { if(somethingelse) { // if both evaluate true. dosomething(); } else { // if first if true second not. dosomethingelse(); } } else { // if first evaluates false. dosomethingdifferent(); } now, me, looks horrific. have cleaner way of representing logic? the question as-is has 3 cases: something & somethingelse , something & !somethingelse , , !something . alternative break out if-else 3 branches: if(something & somethingelse) { // if both evaluate true. dosomething(); } elif(something) { // explicit test of somethingelse falsity not required // if first if true second not. dosomethingelse(); } else { // if first evaluates false. dosomethingdifferent(); } for such simple case, prefer flatten structure above. more complex cases, can end being simpler nest, or better reduce tests kind of structure (a l...
