Why can't I use an OR operator in a switch case for strings in C#? -


it says cannot use or on 2 strings in switch case (dental || vision). placing each option in own separate case work or messing syntax? thanks

            switch (gr.plantypefocus){                 case "medical":                     createplanformedical();                     break;                 case "dental" || "vision":                     //createplanfordental_vision                     break;                 case "ltd" || "life":                     //createplanforltd_life                     break;             }         }

technically achieve 'or' using fall through 

switch (gr.plantypefocus){    case "medical":       createplanformedical();       break;    case "dental":    case "vision":        //createplanfordental_vision        break;     case "ltd":     case "life":        //createplanforltd_life        break;  }

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
