I have a few years behind me ofĬlojure with a product deployed in production since 2009. I recently had an interview with a big corporation. Functional programming lowers this burden, because your APIs tend to exclude the possibility of using them in "the wrong way." It does this, however, at the cost of learning some new abstractions, and for some this learning is difficult because you can no longer think in terms of the traditional nouns and verbs instead FP requires lots of thinking in terms of layered abstractions that are frankly hard to describe in English (or, indeed, most natural languages.) This ability to sidestep breaks down when you've got a number of people working on the same codebase, though mutation-oriented APIs require that you call them in a certain order, which must be documented extensively and require the documentation to be carefully observed.

Basically, programmers who have grown up around mutation-oriented approaches have an idea of how to solve problems, and can't readily see the potential errors that those approaches introduce because they've learned to automatically sidestep them, so the possibility of excluding those errors at the type level (I'm biased towards strongly-typed FP) doesn't initially seem to provide much value. In short, our experience has been that *new* developers (for example, a mathematician we hired with very little programming experience in general) have no difficulty at all in adopting functional programming idioms, whereas those who come from a strongly mutation-oriented programming background tend to struggle with understanding the utility of the novel abstractions that FP exposes in the context of their existing knowledge.

My company, uses Scala extensively, in a heavily functional style (liberal use of scalaz, etc.) and so while I certainly don't fall into the "not yet using FP" camp, I can speak to a degree with respect to challenges that companies can expect in adopting a functional style of programming and/or a functional language.

A recent example is Datomic which was created in Clojure and, as Rich Hickey explains in "Writing Datomic in Clojure", benefits from functional concepts.īut where is functional programming in the industry and particularly the enterprise? Java and other languages still reign in the enterprise. Concepts like Immutability are essential to many functional languages and promise to remove whole classes of bugs (race conditions, etc), improve scalability (locking becomes unnecessary) and bring new capabilities (versioning stores over destructive ones).

Functional programming promises to raise the abstraction of code and to help to escape the micromanaging prevalent in imperative programming.
