Possible Duplicate:Choosing a functional programming language I am a C++ programmer looking to learn a functional language as a hobby and out of sheer curiosity. I am not looking to be an expert, but just to get a grasp on functional programming. This language should be simple to learn and have good tutorials and resources for beginners. Are there any such languages?
Which functional language is good for a beginner?
learning;functional programming
I've found that Haskell has a number of good resources available. It's also a purely functional language, meaning that any identifiers are immutable. As far as resources to learn the language, it has a comprehensive website and a highly recommended tutorial that is also available for purchase as a book. Real World Haskell is also another good book available for purchase or online for free. Haskell is also somewhat common on Stack Overflow, with over 4000 questions asked and many answered.However, one of your requirements is simple to learn. That's hard to judge. Coming from a C++ background, I suspect that you have a strong object-oriented and/or procedural background. Functional programming requires a totally different thought process - it will warp your mind, but it will also make you a better engineer if you are able to think in a new and very different way.
