Your array is storing the references for the single date object and everytime when setDate is called each of them are getting updated with new date value,,To echo the other answers, the issue is that the element being pushed to the array isn't a value which stays the same - it refers to a Date object which changes in the loop, so all references to date1 stored in alldates are set to the final value of date1

Example_snippet/controller/utility/_javascript.js/ for (var i=0; date1 <= date2; . . .
for (var i = 0; date1 <= date2; date1.setDate(date1.getDate() + 1), i++) {
   alldates.push(new Date(date1));
}

alert(alldates.join('\n'));
Step 2 continued with while( date1 <= date2 ) { al. . .
while (date1 <= date2) {
   alldates.push(new Date(date1));
   date1.setDate(date1.getDate() + 1);
}
