How I use to destructure Arrays:
```js
const nums = [1,2,3];
const [a, _, c];
(a === 1) // true
(c === 3) // true
```

Problem is this **_** is not needed and will cause problems with some ESLint
setups. For example they might not allow unused variables. Turnes out you
can just leave that spot blank!

```js
const nums = [1,2,3];
const [a, , c];
(a === 1) // true
(c === 3) // true
```
