Radio buttons issue with OR javascript -


could me understand correct syntax or operator in javascript. using || in script not work. have radio button list 4 values. drop down list visible on value 2 or 3. can working no problem single value of 2 no dice when add || 3. advise? in advance.

    function showconvert() {         if (radconvert.getvalue() == 2 || 3) {             frmactivate.getitembyname("converthide").setvisible(true);         }         else {             frmactivate.getitembyname("converthide").setvisible(false);         }     }; 

(radconvert.getvalue() == 2 || radconvert.getvalue() == 3)    2||3 =2

|| means if left not falsy use right

eg. 

function(option){  option = option || {};  }

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...
