###Unhandled Rejection Tracking

Several promise libraries such as bluebird and when as well as some native promise implementations offer potentially unhandled rejection tracking. This means that the following:

we're discussing how we can safely abort on unhandled rejections and obtain meaningful debugging information. Related reading: https://gist.github.com/misterdjules/2969aa1b5e6440a7e401#file-post-mortem-debugging-with-promises-md.

Part 1: Why bubbling is good

We start with the following code

function startListening(server, cb) {
  server.listen(99999, 'localhost', cb)
}

prettier(yourcode) {
    log("Your Code in prettier format");
}
