Did anyone else find this article lacking? I was hoping to learn a bit more about real world examples of functional programming, but all this really did was state some high level ideas of what you could benefit by using a functional programming language like F#.<p>It is still not clear to me what the advantages of using a functional language like F# vs writing C# code that avoids side effects and mutating objects in functions. If anyone could share any articles or books on the subject, I would really appreciate it.
