Gluing things together
Gluing things together One of the most important things in coding is how to hold it together. In this short article I will share some thoughts on callbacks, events, observables, promises and tasks. This is what I have experienced in my time programming and I would be glad if you could share if you don't agree with me on something. Why callbacks are bad When I started programming some years ago I started with C# and Javascript. While .NET already had the Event in Javascript callbacks were everywhere. Then the word "callback hell" was coined. In short callbacks and also Events for that matter are bad because they defere the code execution to some other place which can be hard to find especially when you are following from one callback to the next for multiple steps. Therefore it pollutes the code and can separate concern which should not be separated. Why callbacks can be good Defered execution is not always bad. To create modulation and structure callbacks an
