const destinations = [

With an array of several objects that constitute cities/airports like the 2 objects above, the user will have to select one object as origin and the other as destination. What I'm trying to find out is how to catch the x and y coordinates of each chosen origin and destination to calculate the distance between the two points and be able to provide distance in km, time and flight cost.
