negative-array
Negative array index support array[-1]
using ES2015 Proxy
JavaScript doesn't natively support the use of a negative index to get items backwards from the end, but with ES2015 Proxy it's possible. Take a look at the source to see how simple it is to implement and read this short article about it.
Note: With Node.js 16.6.0, you can now use Array#at()
instead of this package.
Install
$ npm install negative-array
Usage
import negativeArray from 'negative-array';
const unicorn = negativeArray(['🐴', '🎂', '🌈']);
console.log(unicorn[-1]);
