Question about switch statement 1

[ttomasko]

Hello,
Is it possible to use the switch statement with inequalities?

For instance, the following does not work.

Tom

var x = 4;
switch(x){
		case <5:
		alert("do something");
		break;
		case 5:
		alert("do something more");		
		break;
		case >5:
		alert("do something really big");
		break;
	}//end switch

No, it's not possible. Why not using the if statement?

[tt]var x = 4;
switch(true){
case x<5:
alert("do something");
break;
case x==5:
alert("do something more");
break;
case x>5:
alert("do something really big");
break;
}//end switch
[/tt]
ps: In .net, constant expression is enforced in the case conditional to avoid possible side-effect and this kind of construction will no longer allowed there. Just a note.
