While you're at it, fix the line length to 80 chars.

            "Now is the time for all good men to come to the aid of the party."
 var s1 = base.substring(0, 64);
 var s2 = base.substring(66, 130);
 
 var o = new Object();
 o[s1] = 1;
 o[s2] = 2;
 
 var first_time = true;
 
 for (var x in o) {
   assertTrue(o[x] == 2, "expect 2");
   assertTrue(first_time, "once only");
   first_time = false;
 }
