The Functional Programming for the Real World book explains essential concepts of the functional programming paradigm using examples in C# 3.0 and F#. In this article we look at one very important advantage of using one of the core functional concepts - immutability.

Czech Republic

I live in Prague, the capital city of Czech republic (most of the time Smile | :)

). I've been very interested in functional programming recently and I have a passion for the new Microsoft F# language. I'm writing a book about Functional Programming in the Real World that shows the ideas using examples in C# 3.0 and F#.

I've been Microsoft MVP (for C#) since 2004 and I'm one of the most active members of the F# community. I'm a computer science student at Charles University of Prague. My hobbies include photography, fractals and of course many things related to computers (except fixing them). My favorite book writers are Terry Pratchett and Philip K Dick and I like paintings by M. C. Escher.
