Advance to the next item in the array looping when hitting the end.


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'
