destructure object in javascript es6 when keys are integers

Question

When we have an object in JS like

var obj = {a: "apple", p: "pen"};

then we can destructure it as follows

 var {a, p} = obj; /* a = 'apple', p = 'pen' */

i want to know in case when keys are integers, how can we destructure it ? since we cannot declare integers as variable name

 var obj = {0: 'pineapple', 1: 'pen'};

you can use `keys = Object.keys(obj)` it will give the array of all the keys, then you can access any value by using the keys, like `a=obj[keys[index]]`, is this what you want ?? — Mayank Shukla, Dec 15 '16 at 06:30
Is this an array-like object such as `arguments` or `NodeList`? Or is this an object where there are other string properties? If it's array-like, you can use array destructuring. — 4castle, Dec 15 '16 at 06:31

var {0:a, 1:b} = obj;

@4castle, no, because the obj doesn't implement the iterable interface. – Thomas Dec 15 '16 at 06:36
