 JavaScript doesn't natively support the use of a negative index to get items backwards from the end, but with [ES2015 Proxy](http://soft.vub.ac.be/~tvcutsem/proxies/) it's possible. Take a look at the [source](index.js) to see how simple it is to implement and read this [short article](http://dailyjs.com/2013/11/15/negative-array/) about it.
 
+**Note:** With [Node.js 16.6.0](https://nodejs.org/en/blog/release/v16.6.0/), you can now use `Array#at()` instead of this package.
