which functional language to learn reddit

Do not post questions that are completely unrelated to programming, software engineering, and related fields. When I was playing with Ocaml, I tried to use the language as it was not designed to be used. In learning Haskell you will learn about lazy evaluation, currying, pure functions, and many other functional concepts. Udemy coupon links are ok: the discount adds "additional value". The first line just provides a function signature (input is a list of integers, output is a single integer. I think their best one is about $120 and they have a package deal of 3 for $200. I would say Haskell would be a better fit for him/her. And in a fcuntion that takes in a string and returns a string, you actually also increase an int counter field from said object. Functional programming concepts can be taken and used in any language, but learning a pure functional language forces you to really use the concepts. Perhaps I need a better book/tutorial. I'd like to become a better computational thinker and have heard functional programming may help with that. use the following search parameters to narrow your results: If you need help debugging, you must include: See debugging question guidelines for more info. After all, the one you already speak if you read this magazine is the world’s most useful and important language. The important thing to note here is that there is no accumulator variable, and you are using recursion instead of looping. [top] [–]Innocent_boy_ 2 points3 points4 points 14 days ago* (0 children). As mentioned in some of the answers above, functional programming languages help you think differently about the problems and this can be very beneficial but not necessarily the best way to go about improving your problem solving abilities. Self promotion from first time posters without prior participation in the subreddit is explicitly forbidden. Passerine is an functional scripting language, blending the rapid iteration of languages like Python with the concise correctness of languages like Ocaml, Rust, and Scheme. Now I'm ready to commit to learning a functional language properly, so I can thoroughly understand the idiom and write useful functional programs. If you got an error, include the. That is something that you should keep in mind when using trend data to determine which programming language to learn next. Could I be me outside of me? Which language should you learn? [–]ZartiBartiMcSchleck 2 points3 points4 points 14 days ago (0 children). If you really want to get into the guts of pure functional programming, suck it up and learn Haskell. I'm a Scheme fan. In OO System, it is much easier to accidently break something. [–]BigDog1920[S] 0 points1 point2 points 13 days ago (2 children). I don't have an awful lot of spare time, and I need to choose between Haskell, ML and OCaml. I'm not a purist and actually want a combination of both worlds. Do not use URL shorteners, referral links or click-trackers.

It's not to say that other functional languages are worse, I personally use Clojure, but Haskell is the best way to really understand the functional paradigm. Or maybe it doesn't matter that much? Learn useful English phrases for discussion and debate. Rendered by PID 9230 on r2-app-0b1d0d6b57f401e47 at 2020-12-27 22:45:12.482303+00:00 running 6abf2be country code: US. If you're worried that F# knowledge won't apply to other functional languages, you shouldn't. That's a side effect. Do not ask for help doing anything illegal or unethical. It is the most basic (and important) concept in functional programmi… The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed.

See our policies on acceptable speech and conduct for more details. Here's a decent introduction: http://www.cs.caltech.edu/courses/cs134/cs134b/book.pdf It also helped, I suppose, that I was taking a course which used OCaml, but I'm learning Haskell on my own. I completely understood "the twist" on how functions were "first-class citizen" as they say, and passing functions as parameters. If you're helping someone, focus on helping OP make forward progress: link to docs, unblock misconceptions, give examples, teach general techniques, ask leading questions, give hints, but no direct solutions. It is also a functional programming language so it offers a different paradigm than object-oriented programming, which will improve your thinking and code sense. © 2020 reddit inc. All rights reserved. In short, link to only your code and be specific about what you want feedback on. Once you understand Haskell, you will be able to write functional code in any language :), New comments cannot be posted and votes cannot be cast, More posts from the programming community, Looks like you're using new Reddit on an old browser. My most recent: figuring out how Text.Printf works, and being able to write my own polymorphic, variadic functions. I found OCaml to be pretty easy to learn since you don't need monads. But you can apply some simple techniques in JS, I found a repo that has the data you are looking for , I hope it helps. For example, linking to some tweet or some half-hearted blog post which links to the page is not ok; but linking to a tweet with interesting replies or to a blog post that does some extra analysis is. So if you want to print something in some function, its type has to have type IO because you are doing at least one IO thing inside the function. I struggle sometimes with seeing solutions to new or novel problems that I had not seen before. For example, say you want to sum a list of numbers. Python can be used for web and desktop applications, GUI-based desktop applications, machine learning, data science, and network servers. Python has been a growing programming language and it shows no signs of disappearing. I would definitely say Haskell, the reason being is that it will force you to write functional code. Why learn a foreign language? That's a disaster waiting to happen a lot of the times. Just thinking about writing code. In order to move beyond the basics, you need to learn your first language well. [–]Hawxe -5 points-4 points-3 points 14 days ago (7 children), It's expensive but I highly highly highly recommend Pragmatic Studio for this. How about a functional language that doesn't stop at just being a functional language, but builds on top of it to create something truly unique. This page is Clojure is a flavor of Lisp with some enhancements for modern computing. erlang because it's already proven in the real world. Microsoft just tweaked it a bit so that it plays well with .NET. Erlang of course. Like already said, it helps you to think in a functional way, that is a program as a series of transformation on data. As for what to learn, I would recommend trying to learn Racket if you want to learn a LISP dialect. [–]DonkeyTron42 0 points1 point2 points 13 days ago (0 children). How much DS/algos do we have to know before we start the course? But the concept of applying functions to immutable data, and side-effect-less functions are concepts worth reading upn. I learned Scheme in college, so I don't want to learn functional programming just for the experience. If you keep jumping from language to language, you won’t get far. I can't explain how it all exactly went down, it was strange. If you are going to learn a functional language learn Elixir. Well, SML and OCaml are both dialects of ML. :P, [–]ZukoBestGirl 0 points1 point2 points 12 days ago (0 children), fair enough, but you could still pass functions as parameters :P, [–]Open_Ad1472 0 points1 point2 points 13 days ago (3 children), Lie in bed and think. This includes piracy: asking for or posting links to pirated material is strictly forbidden and can result in an instant and permanent ban. Functional programming concepts can be taken and used in any language, but learning a pure functional language forces you to really use the concepts. Press question mark to learn the rest of the keyboard shortcuts, http://www.cs.caltech.edu/courses/cs134/cs134b/book.pdf. You treat data as immutable, and you are really forced to think about any side effects functions may have. Aka you have a standard OOP object. Both languages are difficult to learn, but if you know C, switch from it to C++ or any other language is easy. In my attempts to learn Haskell so far, I've been using "Learn you a Haskell for Great Good!" Do not request reviews for, promote, or showcase some app or website you've written. Haskell is also a pure functional programming language, meaning that side effects (printing, accessing a database, sending an http request, ...) are checked by the type system. Clojure is a modern functional programming language from 2007 based on Lisp, a language that first appeared in 1958 with a unique parenthetical syntax. It's also good for breaking down problems just into operations (point-free style), but I never got that far. [–]NoManufacture 0 points1 point2 points 13 days ago (0 children). I really don't want to put you off Ocaml though. (The following is C.). Then it uses x and xs in the function (x + sum xs) which means "return x + the sum of the rest of the elements" (exactly what was in our recursive definition!). But if you want to ram your head on the brick wall of purity until it makes sense, you need Haskell. Not necessarily the best rubric to use when selecting a book. It is a modern language that is being used in industry and has some great books/classes made for it. However, the OP wanted to get into pure FP - and Erlang cuts corners there, for the sake of practicality. I went with prolog at college. They'll both come right up on Google. I don't know much about Haskell other than I've heard the learning curve is quite steep. It is a free, open-source programming language with extensive support modules and community development, easy integration with web services, user-friendly data structures, and GUI-based desktop applications. There is no going back now and I regret nothing. It has been a really long time since I did anything in Haskell, but as I remember it helped me think about problems as transformations of data types and working with streams. All links must link directly to the destination page. What should I learn to be able to build my own Linux shell? The Arabic language is quickly becoming a seriously worthwhile investment for those hoping to reach the growing economies in the Middle East and Africa. Elixir is a good choice for beginner developers looking for their first functional language to learn, as it’s a high-level language. It changes completely how you think and opens up so many possibilities. We don’t want to give you yet another ranking, but instead, show you 10 widely used programming languages in 2018 and how people are using them. [–]piano2020 0 points1 point2 points 13 days ago (0 children). I'd had trouble understanding the difference between the two types but your examples really made it click. Tech support and hardware recommendation questions count as "completely unrelated". Haskell, I have chosen Scala because as a Java developer, I found learning Scala is easy than learning Haskell . I'm surprised you left out the classics: Lisp and Scheme. Your post should not "feel spammy". (self.learnprogramming). It's all free and online. You can opt out by replying with backtickopt6 to this comment. Hint: functions can be instances of a typeclass. For example, in Haskell you don’t have normal for/while loops, you only have recursion/list comprehension. Asking for code reviews is ok as long as you follow the relevant policies. Provide functional language as students are ready to learn. Distinguishing between tasteless and tasteful self-promotion is inherently subjective. Not fixing somebody’s else’s sh#t. you might want to start with lisp, then haskell or ML. Replicating myself. Trying to circumvent the terms of services of a website also counts as unethical behavior. It's a cool language. For example working through algorithm questions can be a great way to improve - even though it can sometimes be mentally challenging since we are not necessarily used to this form of problem solving, but many engineers would agree that leetcode can make you a better software engineer ( however, not being able to solve these problems doesn’t make you a worse software engineer - just keep that in mind ), [–]SpecificMachine1 3 points4 points5 points 14 days ago (0 children), Lisp (at a surface level, anyway) helps you think about programs the way the compiler sees them. I just think that if it's your first foray into the world of FP, Scheme (or Clojure) may provide an easier transition. The syntax is often compared to the ever-popular “ Ruby ” for its simplicity and ease of comprehension. It is also oriented to manipulating lists, and the source code is lists, so transitively it's set up for manipulating source code. F# is a member of the ML family of languages. Interested in learning a new language but don’t know where to start? If your question is similar to one in the FAQ, explain how it's different. [–]backtickbot -1 points0 points1 point 13 days ago (0 children). Clojure added features like immutable data structures to Lisp. I'm employed doing Erlang full-time and couldn't be happier. What is the next line? [–]DazzlingDifficulty70 0 points1 point2 points 13 days ago (3 children). Programmers anthem: “Life is but a dream.”, [–]NoManufacture 0 points1 point2 points 13 days ago (1 child). I would rather learn some functional language for practical reasons. The sum (x:xs) uses pattern matching to separate the first element (the "head") of the list (x) from the rest of the list (xs, called the "tail"). and join one of thousands of communities. Most of the literature on functional programming — not just academic papers, but blogs and other online resources — has code samples in Haskell. [–]Open_Ad1472 0 points1 point2 points 13 days ago (0 children). I have already learned Ocaml. They do really incredible courses there. It's probably the simplest and easiest to understand functional language of all and at the same time, designed to be practical. This post was written before I knew about Clojure however, and I would probably recommend Clojure over Scheme since it's so much more practical. Follow reddiquette: behave professionally and civilly at all times. Also, because of its fundamentals and uses over the years, a … Are there classes in your area? I found Ocaml unsatisfying in this regard because many libraries use mutable data, and it supports regular old arrays. policies on acceptable speech and conduct. I have only studied a bit of Algorithms but I've gone through a few intro programming courses. The sum [] = 0 means that if you pass an empty list to sum, then it will return 0. More formally, it mapsan item from one set to another set. If you were choosing between those two, I'd go with OCaml since it is a more popular and hence better supported language--it has a debugger, for instance, whereas SML does not. Lisp falls into the category of functional-but-not-purely-functional. I'd say Clojure is more focused on flexibility and Haskell is more focused on safety. Do not ask for or post a complete solution to a problem. As a side note, JavaScript doesn't support "true" Functional Programming, as in it doesn't have the specific language constructs, methods are not prime citizens, objects are. I really like exploring other languages, but up until this year, at I know Haskell programmers that are afraid when they have to code in Java, because the compiler does much less help there. When posting some resource or tutorial you've made, you must follow our self-promotion policies. 1 on this list primarily due to low engagement across GitHub, Stack Overflow, Freenode, Reddit, Twitter, and Facebook. Functional languages, purely functional ones, help you think about how to do stuff, without side effects. It also teaches you how to write proper tests, and testable code. I only know of Haskell that you can go to a codebase of 10 years, hop right in and change the implementation of one function deep inside the system, and when it typechecks, then the whole system works too. Functional programming is just a must for me, and I just don't want to give it up under any circumstances. F# is a perfectly good place to start learning functional languages. The book, Clojure for the Brave and True, does a pretty good of explaining it. If you are using a procedural language, you may use a sum variable with a loop which has a counter (i) and every time you loop, you add to sum and increment i. Read our FAQ and search old posts before asking your question. So where to begin? [–]PeterJHoburg 27 points28 points29 points 14 days ago (8 children). Elixir is so much fun and Phoenix is such an amazing framework, [–]BigDog1920[S] 0 points1 point2 points 13 days ago (1 child), [–]Hawxe -1 points0 points1 point 13 days ago (0 children). This video and article is for those who want to learn a second foreign language besides English and for English native speakers who want to master a foreign language, but who may not know which language to learn. Once you understand Haskell, you will be able to … F#, Scala, Clojure. For example, with dynamic programming problems it is useful to be able to think recursively so that you can derive the recursive formulation of the problem so that you can then apply dynamic programming via memoisation or as a table. Haskell is pretty good (although I'm not great at it). C++ Book Recommendatins: Using older editions of Stroustrup's "The C++ Programming Language". You may not ask for or offer payment of any kind (monetary or otherwise) when giving or receiving help. Communicate to others the same way you would at your workplace. IO in Haskell is quite different from IO in imperative languages. Though there are many functional programming languages available e.g. Generally speaking side-effects are frawned uppon because if I don't know the code, I just see your method name, I use it, and it does something besides what the name, input and output suggest. A lot of languages let you do stuff that is not ok, such as side effects. See conceptual questions guidelines for more info. This enables lots of things and makes a lot of things more When working on a problem, try solving it on your own first and ask for help on specific parts you're stuck with. The recursive definition of the sum of a list is something like: In Haskell, you would write the above as: You may be able to see some similarities to the recursive definition above. They use side-effect-free functions as a basic building block in the language. The best, the best version of myself while singing “row, row, row your boat gently down the stream”. I've been enjoying OCaml as well, lately. In short, your posting history should not be predominantly self-promotional and your resource should be high-quality and complete. I heard that learning a functional programming language like Lisp or Haskell can help with problem solving. It changes how you write code, and can end up with you writing more clear code. You ok there bud? ML seems more foundational, Haskell more theoretical and cool, OCaml more practical. But I had no idea what was going on, I didn't understand a single thing, while the rest of my class were doing ... fine - ish. When in doubt, message the mods and ask them to review your post. It made no. [–]Hawxe -3 points-2 points-1 points 13 days ago (2 children), https://pragmaticstudio.com/courses/elixir, [–]DazzlingDifficulty70 0 points1 point2 points 13 days ago (1 child). I didn't want this. Ocaml wants you to use a more familiar solution. All these different features of functional languages make you think about problems a bit differently. Instead you basically use the function call stack to implicitly store the accumulation. If so why? Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Is this true? Ocaml is very practical and lets you do pretty much anything you want, stylistically. [–]hassium 0 points1 point2 points 13 days ago (0 children). How does clojure differ from Haskell? Here are some common terms you'll see all of the time: 1. I'm familiar with Haskell and OCaml and functional theory by going through tutorials and reading various blog posts. Python-based web development framework like Django, Pyramid and Turbo Gearhave found more and more popularity. Function - A function is a construct that will produce an output when given an input.
