how can I get the last element in the json array in the seats object. I want to get the countryid of with the value of 845, however this json is dynamic so i want to get the last element in the seats object. My api is structured like this. Thank you in advance.

{

expirationDate:April 21, 2017,

remainingDays:325,

seats:[{activeStatus:S,pid:TE70,firstName:TE70,countryid:840},

        {activeStatus:Y,pid:TE80,firstName:TE80,countryid:845}]

 }
