The end result of the most common method, callbacks, is difficult to read code and a decidedly difficult to read codebase for developers used to most blocking procedural languages. Promises, added natively to Node in the 4.x release, offer a better way to handle the parallel operation of blocking operations in an asynchronous environment.

thank you man i really needed this. but is it possible to get this slid show or at least the examples provided within the slides ?

[badaljain]

do you have github link to your demo project?

call a promise wrapped in a promise with a promise that wraps a fuction that's not a
