getting last element in JSON not working

Question

I am trying to take the last element in a JSON. I know order is not preserved, but the keys are unix timestamps so I can just sort. I am working from this question:

get last element of a json object in javascript

But I get nothing logged to the console and no errors.

my code:

var mydata = {"1509937402379":"7348.01","1509937412486":"7348.01","1509937422253":"7348.01","1509937426286":"7348.01","1509937430066":"7345.54"}

console.log(mydata[Object.keys(obj).sort().pop()]);

@jhpratt the order of object is not preserved consistently. Namely `Object.keys` does not preserve the order. More at https://stackoverflow.com/a/30919039/1043231 — Dominik, Nov 06 '17 at 03:28

You missed.. .You require to use Object.keys(mydata).

var mydata = {"1509937402379":"7348.01","1509937412486":"7348.01","1509937422253":"7348.01","1509937426286":"7348.01","1509937430066":"7345.54"}
