A problem caused by careless use of variable type: TC code

   var value=new Array(1024,768,250,480,540,800,600,933,700);
   for(var i in value)
   {
     Log.Message((1+i)<5?(i):(i+1))
   }

 The result for this program:

01  11  21  31  41  51  61  71  81

 

seems weird, what I expexted is : 0 1 2 3 5 6 7 8 9

 

After debug found root cause is that:

for(var i in value)

 

here var i is treated as string later, NOT as intenger!

 

Correct Code should be:

  var value=new Array(1024,768,250,480,540,800,600,933,700);
   for(var i in value)
   {
     i=parseInt(i);
     Log.Message((1+i)<5?(i):(i+1))
   }
