I am developing an Angular web service for creating photo journeys and displaying them on a map using Leaflet. When I upload the pictures, I get their coordinates from their EXIF data and their DateTimeOriginal from it which returns string like this:

and then save them in array for a further connecting with paths on a map.

I have issues with sorting this array by timestamps in order to connect the markers on the map properly:

How can I sort by time-stamp?

Sorted by: Reset to default 5

Seems that the dates are invalid. If it would be properly formatted like this ("2012/10/24 16:37:44") you might do this:

const a = new Date("2012/10/24 16:37:44").getTime();

For example, you would map over items in this array

function sortNumber(a,b) {
    return a - b;
}

items.map(item => new Date(item.timestamp).getTime()).sort(sortNumber);
