    Promises are used as a proxy for a value that isn't known at the time it's created. While in callback functions your code executes in a nested callback, Promises provide an alternative approach that allows you to access asynchronous method return values with synchronous methods.

    "I gave this a try and programming within my business went much more smoothly. This is not for a beginner. I have good IT people so they were easily able to figure this out. If ou are not in that scenario, I would approach this with caution. Besides that, I recommend to anyone. "

    "I'm a new software developer just starting to get my footing in JavaScript. I can see the great advantage of Async.js as a library of utilities, and I anticipate using it more as time goes on. But I wish there were more explicit instructions and pointers for the beginner like myself."

    Iterators and Generators (JavaScript)
    An iterator is an object that is used to traverse a container object like a list. In JavaScript, an iterator object is not a distinct built-in object, but is an object that implements a next method to access the next item in the container object.

    "This solution provides me javascript options for iterators and generators which from the description on the website dont seem to define themselves as callbacks. I'm not entirely sure if these would even be considered callback alternatives as its not mentioned anywhere and doesn't compare or list any other alternatives. I'm not knowledgeable enough about javascript to know if this page is even going to be helpful to me. "
