Get the last element in json array

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}]
}

Answer

You can do this by accessing the jsonData.seats array by index, index of the last item being equal to jsonData.seats.length-1

simply:

var countryId = jsonData.seats[jsonData.seats.length-1].countryid
