This reminds me lack of a Range operator in javascript. The one like in Pascal and PL/SQL http://www.techonthenet.com/oracle/loops/for_loop.php Which can also be used in for loop Many times when coding I need something like that in Javascript too And I suggest ... (three dots) as the operator because : has other uses in javascript and .. is used by E4X Example usage are. startIndex = 2; lastIndex = 5; myRange = startIndex ... lastIndex; a[myRange] // array slice instead of if(a >= 2 && a <= 5) doSomething(); we could simplify code as if(a in 2 ... 5) doSomething(); or for(i in 2 ... 5) print(i); we should also allow usage for Sting and Date range checking, like if('Dmitry' in 'Biju' ... 'Jordan') doSomething(); and if( (new Date(2010,1,1)) in (new Date(2008,1,1)) ... (new Date(2012,1,1))) doSomething(); _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
