A dead simple round-robin array iterator
Install
npm install roundroundUsage
var roundround = require('roundround');
// Initialize RoundRound with any Array (null or undefined are ok as well, so no
// guards necessary)
var rr = roundround([1,2,3]);
// Then call the result to get the next element in the array
rr(); // => 1
rr(); // => 2
rr(); // => 3
// When reaching the end of the internal array, the iterator starts over from
// the beginning
rr(); // => 1
// You can also specify an index from where RoundRound should start
var rr = roundround([1,2,3], 1);
rr(); // => 2License
