Attach Boolean to an Array

Hello all,

Is there a possibility to attach a boolean to specific array?

Like for example:

var flag= true;
var myArray= new Array;  

for(i=0; i<myArray.length; i+=1)
   result = doFunction();
   if(result == true)
      myArray*.flag = true;
      myArray*.flag = false;

I’ll need to display that particular item in the array if it returns “true” in the flag.

Help will be greatly appreciated. Thanks!
