Get consecutively unique elements from an array
Useful for things like slideshows where you don't want to have the same slide twice in a row.
$ npm install unique-random-array
const uniqueRandomArray = require('unique-random-array'); const random = uniqueRandomArray([1, 2, 3, 4]); console.log(random(), random(), random(), random()); //=> 4 2 1 4
Returns a function, that when called, will return a random element that's never the same as the previous.
