getting the last item in a javascript object

Question

If I have an object like:

{ \'a\' : \'apple\', \'b\' : \'banana\', \'c\' : \'carrot\' }

If I don\'t know in advance that the list goes up

Answer 1

Solution using the destructuring assignment syntax of ES6:

var temp = { 'a' : 'apple', 'b' : 'banana', 'c' : 'carrot' };
var { [Object.keys(temp).pop()]: lastItem } = temp;
console.info(lastItem); //"carrot"
