You could use a single for loop, while loop , Array.prototype.map(), Array.prototype.concat() , String.prototype.replace()

var n = 0,
  min = 5,
  periods = [" AM", " PM"],
  times = [],
  hours = [12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];

for (var i = 0; i < hours.length; i++) {
  times.push(hours[i] + ":" + n + n + periods[0]);
  while (n < 60 - min) {
    times.push(hours[i] + ":" + ((n += 5) < 10 ? "O" + n : n) + periods[0])
  }
  n = 0;
}

times = times.concat(times.slice(0).map(function(time) {
  return time.replace(periods[0], periods[1])
}));

console.log(times)
