function convertTo12HourTime(time) {
  const hours = parseInt(time.substr(0, 2));
  const minutes = time.substr(3, 2);
  const period = getAMPM(hours);
  const twelveHourFormat = convertTo12HourFormat(hours);
  return `${twelveHourFormat}:${minutes} ${period}`;
}

const twentyFourHourTime = '15:30';
const twelveHourTime = convertTo12HourTime(twentyFourHourTime);

Code Explanation

• The convertTo12HourFormat function takes the 24-hour format hours and converts them to 12-hour format.
• The getAMPM function determines whether the time is AM or PM based on the input hours.
• The convertTo12HourTime function parses the input time, converts the hours to 12-hour format, and returns the time in the format "hh:mm AM/PM".
• Lastly, an example is shown, converting the 24-hour time '15:30' to 12-hour time, which results in '3:30 PM'. ```
