Sorting array of objects by time using javascript

Question

So here's what my array of objects currently looks like.

var array = 
[
{"time":"1:00 AM"}
{"time":"2:15 AM"}
{"time":"3:00 AM"}
{"time":"4:30 AM"}
{"time":"5:00 AM"}
{"time":"6:00 AM"}
{"time":"7:00 AM"}
{"time":"8:00 AM"}
{"time":"9:00 AM"}
{"time":"10:00 AM"}
{"time":"11:00 AM"}
{"time":"12:00 PM"}
{"time":"1:00 PM"}
{"time":"2:00 PM"}
{"time":"12:00 AM"}
{"time":"12:15 AM"}
{"time":"12:30 AM"}
]

I am trying to order them into the following order

var array = 
[
{"time":"12:00 AM"}
{"time":"12:15 AM"}
{"time":"12:30 AM"}
{"time":"1:00 AM"}
{"time":"2:15 AM"}
{"time":"3:00 AM"}
{"time":"4:30 AM"}
{"time":"5:00 AM"}
{"time":"6:00 AM"}
{"time":"7:00 AM"}
{"time":"8:00 AM"}
{"time":"9:00 AM"}
{"time":"10:00 AM"}
{"time":"11:00 AM"}
{"time":"12:00 PM"}
{"time":"1:00 PM"}
{"time":"2:00 PM"}
]

How would I do this?

I've tried sorting but the AM and PM is throwing things offer. I really appreciate all of the efforts of this community in helping people like me understand how to code better :)

Please provide enough code so others can better understand or reproduce the problem. — Community, Sep 22 '21 at 10:27

var objs = [
    {ref_time:"00:30 pm"},
    {ref_time:"10:30 pm"},
    {ref_time:"00:30 pm"},
    {ref_time:"03:30 pm"},
    {ref_time:"04:30 am"},
    {ref_time:"02:30 pm"},
    {ref_time:"11:30 am"},
    {ref_time:"09:30 pm"}
]  
 
function compare(a,b) {
    var time1 = parseFloat(a.ref_time.replace(':','.').replace(/[^\d.-]/g, ''));
    var time2 = parseFloat(b.ref_time.replace(':','.').replace(/[^\d.-]/g, ''));
    if(a.ref_time.match(/.*pm/)) time1 += 12; if(b.ref_time.match(/.*pm/)) time2 += 12;
    if (time1 < time2) return -1;
    if (time1 > time2) return 1;
    return 0;
}  

objs.sort(compare);

console.log(objs);

I am currently on the phone so testing code is hard but i can give you a idea. Since AM and PM are the ones screwing you over you could try to make a function that convert "2:00 PM" to "14:00". This should be relative simple.

detect if its am or pm.
strip the "am" or pm tag.
if its pm get the time and add 12 hours.
Use the new time to sort.
