Incrementing array index error

[Virusescu]

So.
I've got the following setup
tc is an array of objects. Each object has a num property.
cc is another array defined earlyer as
cc = [0,0,0,0,0,0,0];
with a length == the max tc[x].num value

Code: Select all

for (var x = 0; x < tc.length; x ++)
   {
	cc [tc [x].num] ++;
	
   }

The previous code yelds this error

I've tested and find out that the folowing code works ok. I hope it's incrementing the value as I haven't tested it throughly

Code: Select all

for (var x = 0; x < tc.length; x ++)
   {
        cc [tc [x].num] = cc [tc [x].num] +1;
   }

I would suggest to unroll the expression into a simpler one, which also would help in making the code more readable

Code: Select all

for (var x = 0; x < tc.length; x ++)
{
   var id = tc [x].num 
   cc [id]++
}
