Callback Hell (2016)
As a curious and perhaps naive aside, I&#x27;ve been wondering why the programmer should need to care about asynchronous execution of code at all. Can&#x27;t it all be abstracted under a procedural layer and let the OS worry about not blocking anything? The advent of promises, async.js, and other paradigms tell me that people still kind of want to write code that does one thing after another, then another, then another.
