I have this array:
[{start_date: "2022-12-05T04:00:00Z" ,distance: 1000, time: 3600}
,{start_date: "2022-02-07T04:00:00Z" ,distance: 1500, time: 6400},
{start_date: "2022-12-08T04:00:00Z" ,distance: 1000, time: 1300}]
I want to add the distance and time values grouping them by the month indicated by the start_date value. For example, if two start_dates have the same month 2022-12-01 and 2022-12-08, how can I add the distance and time values of those two months?
so i get a new array like this:
[{month: 12 ,total distance: 2000, total time: 4900},
{month: 02 , total distance: 1500, total time: 6400} ]
