I have an array of objects as follows :
let cars = [ {\"id\":20,\"mileage\":41300,\"make\":\"Golf\", initialRegistration:\"09/02/2010\"}, {\"id\":21
Your sorting way is proper, just change the date format in cars array, make it MM:DD:YYYY, or YYYY:MM:DD it will work, because these are the formats that Date parse accept.
