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

Answer 1

using HH:mm will convert 12 hrs format to 24hrs while using hh:mm will convert 12hrs format

moment("12:15 PM").format("HH:mm")

Answer 2

var today = new Date();
let options = {  
    hour: "2-digit", minute: "2-digit"  
};  
console.log(today.toLocaleTimeString("en-us", options));
