I want to sort this object by the time at which the order was placed by a user. I want the latest order to be at the beginning of the array and the oldest order at the last. I tried using the sort function, but it only sorted orders for a single month. If orders are placed at different month, it cannot sort the orders.
fetchedOrders.sort( function(a,b) {
var timeA = new Date(a.time);
var timeB = new Date(b.time);
var timeA = new Date.parse(a.time);
var timeB = new Date.parse(b.time);
if(a.time < b.time)
return 1;
if(a.time > b.time)
return -1;
return 0;
});

You are creating Date() objects in your sorting function but you do not use them for comparison. Instead you are comparing the raw time strings from your object.
The raw timestamp is not sort-friendly.
If you really want to use it for sorting it should look like 2021/02/23, 12:44:06 instead of 23/02/2021, 12:44:06

The time comparison cannot be considered correct. You don't even seem to use the date variables you just created. The sort function should be changed as follows.
fetchedOrders.sort( function(a,b) {
var timeA = Date.parse(a.time);
var timeB = Date.parse(b.time);
if(timeA < timeB)
return 1;
if(timeA > timeB)
return -1;
return 0;
});
The Date.parse() function creates a quantifiable representation of the date/time. This is what you should compare in the sort function.

You can convert your time value in YYYY-MM-DD hh:mm:ss format and then lexicographically sort it using string#localeCompare .
const orders = [{ time: '26/01/2021, 10:42:17', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 1253, id: '-MRx5pf06D6Jq-dha9L5' }, { time: '26/01/2021, 20:19:07', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 970, id: '-MRz9rMOBbWcCY-fFDd8' }, { time: '25/01/2021, 15:25:05', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 128, id: '-MRsxyfq3vWm1dFZl_oW' }, { time: '26/01/2021, 20:19:09', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 970, id: '-MRz9ragOIxJXilPF3MB' }, { time: '24/01/2021, 12:16:30', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 2679, id: '-MRn8D25UUj5rRfAJ5EN' }, { time: '23/02/2021, 12:44:06', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 2923, id: '-MUCjE5dAurxRu9Ac6EB' }, { time: '25/01/2021, 15:25:37', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 200, id: '-MRsy5ZvNiIai7U-O5Rj' }, { time: '24/01/2021, 11:44:40', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 1952, id: '-MRn0w2Srovbr3-0vh9j' }, { time: '26/01/2021, 11:09:12', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 1125, id: '-MRxC-8BgmG2InUeUwrV' }, { time: '25/01/2021, 15:27:10', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 286, id: '-MRsyS9Ez1_wIAxqMMIF' }, { time: '27/01/2021, 22:06:46', userId: 'fWXFsnaK8vcHUX4QFVHaBePWvFr2', amount: 6349, id: '-MS3h5JurxnAWlLL8J4l'} ]; orders.sort((a,b) => { const formatDate = (date) => date.replace(/(..)\/(..)\/(....)(.*)/, '$3/$2/$1$4'); return formatDate(a.time).localeCompare(formatDate(b.time)); }); console.log(orders);

Using date formater like moment.js to format the date correctly With moment js we can compare date with milliseconds as possible And format as we want, with isBefore and isAfter method
fetchedOrders.sort( function(a,b) {
var timeA = moment(a.time, 'DD/MM/YYYY, HH:mm:ss');
var timeB = moment(b.time, 'DD/MM/YYYY, HH:mm:ss');
if(timeB.isAfter(timeA, 'minutes'))
return 1;
if( timeB.isBefore(timeA, 'minutes') )
return -1;
return 0;
});
