Convert 12 hour (AM/PM) string to 24 Date object using moment js

Question

I have a output resulting from a timepicker giving 12 hour format of time.

Eg : \"1:45 AM (or) \"12:15 PM\" as **string**

Is there a way to par

Here's how you can set the time of a Date object using a time String.

const date = new Date('1/1/21');
const pm = '2:30 PM';
const am = '11:00 AM';
const noon = '12:00 PM';
const midnight = '12:00 AM';

const mergeDateTime = (date, time) => {
  const parsedTime = moment(time, ['h:mm A']);
  const merged = moment(date).set({
    hours: parsedTime.get('hours'),
    minutes: parsedTime.get('minutes')
  });
  
  return merged.toDate();
};

const resultsList = document.querySelector('#results');

const inputs = [pm, am, noon, midnight];

inputs.forEach((input) => {
  const li = document.createElement('li');
  li.innerText = `${input} ➡ ${mergeDateTime(date, input)}`;
  resultsList.appendChild(li);
});
