Post Mortem Debugging in NodeJS in the Light of Promises

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.

We start with the following code

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

PRETTIER - What is Prettier? Prettier is an opinionated code formatter

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

There are 3 types of executable code in ECMAScript:

When ECMAScript code executes, it always happens within a certain execution context.

	// Concurrency is the key to designing high performance network services.
	// Go's concurrency primitives (goroutines and channels) provide a simple and efficient means
	// of expressing concurrent execution. In this talk we see how tricky concurrency
	// problems can be solved gracefully with simple Go code.
