Such a simple question. But does it have an easy answer? Opening up your code base can seem a bit scary. Everyone can see your (bad) code and commit messages, and it's easier for evil people to find weaknesses or make fake copies of your product. But there are many good reasons for open-sourcing a project. Let's go through some of them.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​​​‌‍​‌​​‌​‌‌‍‌​​‌​‍‌​‌​‍‌‌‍‌​​​​​‌‌‍‌‌​‍‌​‌​‌‍‌​‌‍‌‌​‌​‍‌‌‍​‍‌‍‌​​‌​​​​‍‌‌‍‌‍​​​‍‌​‌​​​​​‌‌‌‍‌​‌‍​‌‌‍‌‌‌‍‌‌‌‍​‌​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​​​‌‍​‌​​‌​‌‌‍‌​​‌​‍‌​‌​‍‌‌‍‌​​​​​‌‌‍‌‌​‍‌​‌​‌‍‌​‌‍‌‌​‌​‍‌‌‍​‍‌‍‌​​‌​​​​‍‌‌‍‌‍​​​‍‌​‌​​​​​‌‌‌‍‌​‌‍​‌‌‍‌‌‌‍‌‌‌‍​‌​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

We all know and appreciate Java Generics. It enables us to say "oh, this is a List of Strings", "oh, this is a Comparator for Integers", and the compiler will forbid you to add numbers to your list, or sorting your List of Strings by comparing Integers. Because it does not make sense. Before Generics was introduced in Java 5.0 in 2004, nothing was stopping you from expressing these nonsensical actions, and things would blow up when running your program, instead of being told already when writing the code that there is no way this will work.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​​‌​​‌​‍​​​‌​‌‌‌‍‌‍‌‍​‌‍​‍​‍‌‌‍​‌‌‍‌‍​‌‌​​‍​‍‌​‌​​‌​​‌‍​​‍​‍‌​‍‌​​‌‍​​‌​‍‌​​‍​‌‌‌‍​‌​‌​‌‍​‌‍‌‍​​‍​​​‌‍​​​​‌‌‍‌​​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​​‌​​‌​‍​​​‌​‌‌‌‍‌‍‌‍​‌‍​‍​‍‌‌‍​‌‌‍‌‍​‌‌​​‍​‍‌​‌​​‌​​‌‍​​‍​‍‌​‍‌​​‌‍​​‌​‍‌​​‍​‌‌‌‍​‌​‌​‌‍​‌‍‌‍​​‍​​​‌‍​​​​‌‌‍‌​​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

Serverless computing has been with us for some years now, and has been "production ready" for quite a while. Services like AWS Lambda, Google Cloud Functions, and Azure Functions allow us to create highly scalable services with minimal overhead where you only pay for what you actually need. Azure Durable Functions is an extension of the Azure Functions family that lets you create stateful functions. This is useful for a lot of different scenarios, including the fan-out/fan-in pattern, which we will look into in this blog post.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​​‌‍‌‌‌‍​‌​‍​​‍‌​‌​‌‍​‍​‌​​‍‌​‌​​​​​​​​‌​​‍‌​‌​​‍‌‌‍​‌‍​‌​‍‌​‍‌​‌‌‍‌‍​‌‌​‍‌‌‍​‌‌‍​​‌‍​​‌​​​​‍‌‍​‍​‍​‌‍​​‌​​​‌​​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​​‌‍‌‌‌‍​‌​‍​​‍‌​‌​‌‍​‍​‌​​‍‌​‌​​​​​​​​‌​​‍‌​‌​​‍‌‌‍​‌‍​‌​‍‌​‍‌​‌‌‍‌‍​‌‌​‍‌‌‍​‌‌‍​​‌‍​​‌​​​​‍‌‍​‍​‍​‌‍​​‌​​​‌​​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

The world of front end frameworks is always evolving. For years it was dominated by jQuery and Backbone, but these days we hear most talk about React and Vue. However, there is another framework that hasn't been talked about so much, namely Svelte.
