My Road to F#
I came from the OOP world, most of my professional work was in Java or C#. The languages were similar, and I could use them interchangably as I built software in each of them for several years. With enough experience in both, I was comfortable with either ecosystem and could generally be productive in either. Sometimes the job required one or the other.

On Linux, I could type a handful of commands into a newly installed system and be up and running.
Sometime around 2005, Java had stagnated while C# was flourishing. They both released generics, but then C# came out with new features like
