Provides a wrapper with helper functions to assist with callback loops
npm install array-wrapperSimple wrapper around arrays providing a inbuilt interator to assist with callback functions
var sampleLinks = ['http://www.google.com', 'http://www.nodejs.org', 'http://www.stackoverflow.com'];
var Wrapper = require('array-wrapper');
var links = new Wrapper(sampleLinks); // builds the wrapper console.log('get first element', links.get()); //gets the first element or the element the wrapper is currently pointing at
console.log('shift the pointer to the second link', links.next()); //shifts the pointer
console.log('get current element (second element)', links.get()); // prints 'http://www.nodejs.org', the next element` console.log('move the pointer to the previous link', links.previous());Pointing the pointer to an out of bounds element returns undefined - it does not differentiate between an array with undefined elements and out of bounds elements
