These features allow for greater program-and sometimes programming-efficiency, but I recommend learning how to program in a fully functional style before using these shortcuts.)Ī fantastic textbook for getting started with Scheme is Structure and Interpretation of Computer Programs. (Note that most functional languages, including Scheme, have support for features that are not purely functional, for instance updating values. After learning Scheme, you'll be well-equipped to recognize and use functional patterns in more complex languages.

But if you want to learn the basics of functional programming, Scheme is hands-down the best.įunctional programming is characterized by programs that are more like mathematical functions than procedures that maintain and update state. Scala is an easy transition for those familiar with Java and object-oriented programming. OCaml is useful with its libraries and healthy community of users. Haskell is beautiful and will teach you to think about programming in a new way.

It shows that large improvements in software notation are possible.Īnswer by Jean Yang, MIT CSAIL, on Quora, I am still a journeyman at Haskell, but I am amazed that it is simultaneously among the most concise, beautiful, and high-performing languages. It challenges my preconceptions about where bugs come from, and how much automated tools can help for instance, SQL injection attacks are compile errors in reasonable Haskell programs, because user-input strings are of a different type than SQL queries. Sure, you might have reversed the operands to division somewhere, but those are the sorts of bugs that are left no more bugs of the form, "Oh, you have to sandwich calls to snark.foo() between calls to blark.openFooWindow() and blark.closeFooWindow(), but they only nest one deep, and we've already opened the window sometimes here, so.".

This is frustrating too, at first, until you have the "Haskell Experience": that once your program compiles, it works. When you settle down to writing code, you'll find there are a lot of compile errors, and they're all type errors.
