Super tiny module that returns the next item in an array when given an item in the array.
If you give it the last item in the array and call next it will loop around and give you the first.
npm install array-next
var next = require('array-next');
// our demo array
var arr = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
// if none specified next should return first
next(arr); // returns 'a'
// when given an item in the array it returns the next one
next(arr, 'a'); // returns 'b'
// it also loops if you give it the last item
next(arr, 'c'); // returns 'a'If you like this, follow @HenrikJoreteg on twitter.
