Nested es6 array destructuring?

Question

Is it possible to nest destructuring?

E.g. I want the first item in an array and in that array I want the first item of that child array.

Given:

let arr = [['foo'], ['bar']];

Is there an easier way to do:

let firstItem = arr[0][0];

Answer 1

Ah figured this out:

let [[firstItem]] = arr;

That would be the equivalent.
