Callback Hell in Nodejs: A Solution With Fiber

See the original posting on DZone Python

Apiumhub developers and any other developers that have worked with Node.js must have encountered a problem when dealing with the asynchronous APIs (I/O) that JavaScript offers; the famous JavaScript Callback. It’s the way JavaScript incorporates responding to events. In this article, I would like to talk about a solution with Fiber when dealing with Node.js Callback Hell. 

Callback Hell in Node.js: JavaScript Callback

The invocation of “A” can be immediate, as in a synchronous callback, or, it can occur later as in an asynchronous callback. It’s actually a simple concept that can be well understood with an example:
