海外TECH	DEV Community	How Does Functional Programming Contribute to Modern Languages?	https://dev.to/typeable/how-does-functional-programming-contribute-to-modern-languages-4gap	How Does Functional Programming Contribute to Modern Languages Author Vladislav LagunovModern programming languages have a large set of various tools and useful features which makes it possible to write quite a different code in the same language for the same task Programming paradigm is a way of thinking in the first place the way the programmer thinks about the data representation and processing In other words programming paradigm exists in the programmer s mind and is not a part of the language Different languages can support a specific paradigm to a varying degree If we open Wikipedia and start reading about the most popular programming languages we ll see that many of them are described as “multi paradigm they allow programming in different styles though some of them will be more convenient to use I FP by In our recent post we spoke about the practical applications of Lisp and mentioned without going into details that it strongly influenced the development of other programming languages Now it s high time to explore this topic in more detail and figure out what contribution functional programming in general not just Lisp has made to the development of other languages Since we use Haskell as the main programming language we couldn t help touching upon this topic In this post we re going to consider several mechanisms which either emerged in the functional programming languages or were most widely used and popularized by these languages eventually turning up in originally non functional languages First class functionsThe distinctive feature of FP style in general is the wide use of functions which become one of the main development tools Let s quickly look through the main definitions describing the differences between the functions and procedures and other similar constructs of non functional languages Higher order function is the function that either takes another function as an argument or returns some function as the result They are also called functionals This behaviour can be implemented even in pure C using function pointers void update user balance int user id double update fn double user gt balance update fn user gt balance First class functions are the ones which you can manipulate in the same way as any other values pass as arguments return as results assign to variables and structure fields Lambda function is the anonymous function Besides the absence of a name support of lambda functions removes other language restrictions on function declarations in some languages i e in C standard function declarations can occur only at the higher level Support of lambda functions implies that the function can be declared in any location where other expressions are valid Lambda functions are mostly used in higher order functions when used in combination they provide convenience and significant shortening of the code Example of a lambda function used to print out the contents of std vectorint main std vector lt int gt v v push back v push back std for each v begin v end int x std cout lt lt x lt lt n Closure is the function that can capture some variables from the context it was declared in without letting the garbage collector erase the data which can be used in this function for as long as the application has the reference to the function itself An example in TypeScript function createClosures The variable can be seen in the functions below let counter The values of fields inc and print are closures return inc gt counter print gt console log counter value counter const c createClosures c inc c inc c print gt gt gt counter value List comprehensionList comprehension allows writing down concisely the processing or generation of lists using existing ones Miranda was one of the first languages to use such syntax which was adopted by Haskell later on similar constructs appeared in “less functional languages such as Python C Ruby As an example let s consider the code in Python and Haskell that creates word combinations using adjectives and nouns These two fragments look very much alike and only have minor syntactical differences don t they Example in Pythonnouns waterfall moon silence adjectives late divine blue phrases a n for n in nouns for a in adjectives gt gt gt late waterfall divine waterfall blue waterfall late moon divine moon blue moon late silence divine silence blue silence The same in Haskellnouns waterfall moon silence adjectives late divine blue phrases a n n lt nouns a lt adjectives gt gt gt late waterfall divine waterfall blue waterfall late moon divine moon blue moon late silence divine silence blue silence Algebraic data typesThese types can also be called ADTs sum types discriminatory unions disjunctive unions coproducts and probably some other clever words Maybe you have the idea of such types under different names but in a few words this is a compound type containing the discriminant field which can be called a tag together with the associated data The following is the Haskell example of such compound type describing the user s possible actions in a hypothetical application implementation TodoMVC Some actions involve the “payload a string or an element ID data UserAction TextInput String EnterPressed EscPressed CheckTodoItem ItemId Bool EditTodoItem ItemId String DeleteTodoItem ItemId ApplyFilter TodoFilterDespite its simplicity and usefulness for modelling domain objects ADTs are rarely supported on a full scale in popular languages and databases Here are some examples implementing similar types Enum in Rust Sealed Classes in Kotlin std variant in C Pattern MatchingPattern Matching is a syntactic construct giving access to the data of the structure consisting of one or several alternatives with different sets of fields the very ADT algebraic type sum enum std variant etc we discussed earlier Pattern Matching resembles the switch case operator you all know from imperative languages However its main advantage is that the compiler checks the access to alternative fields statically by using the information about the expression type while the switch case doesn t prevent errors related to incorrect access to the fields missing cases or redundant checks Pattern Matching is another technique popularized in functional languages where it turned out to be useful Now it is adopted and integrated in various forms in Python Java C Rust and other popular languages Example of state update function in a hypothetical TodoMVC written in the Elm architecture style Pattern Matching is used to analyze the user generated event updateTodoList UserAction gt TodoState gt TodoStateupdateTodoList action oldState case action of TextInput newTitle gt oldState title newTitle EnterPressed gt appendNewItem oldState EscPressed gt stopEditing oldState CheckTodoItem itemId itemChecked gt updateItemById itemId checked itemChecked EditTodoItem itemId itemTitle gt updateItemById itemId title itemTitle DeleteTodoItem itemId gt deleteItembyId itemId oldState ApplyFilter newFilter gt oldState filter newFilter Lazy evaluationsIn most programming languages evaluation is performed when the value is assigned to the variable all arguments are evaluated before the function call strict evaluations The alternative approach is “lazy implying that the evaluation is postponed until the value is actually used Lazy evaluation allows working with infinite data structures writing declarative code with definitions arranged in the order convenient for reading instead of the order of their evaluation If you use the DSL approach lazy evaluations will help you to easily implement such constructs as if then else the values will be evaluated only in the branch you need The history of the term can be traced back to lambda calculus forming part of the theoretical basics of functional programming so no wonder that it s used in FP languages For instance in Haskell everything is evaluated lazily by default Some elements of “laziness can be found in other languages even in pure C the operators amp amp and are lazy as they don t evaluate their second argument if the first one has been evaluated as or correspondingly In higher level languages the more common term is “deferred evaluations which are implemented using generator functions and the “yield keyword Such generators can be found for example in Python or Java ContinuationsContinuation is the “remaining evaluation i e the description of what is to be done with the result of expression for each subexpression in the program An expression gets the continuation in the form of an additional argument and when the result is obtained the current function calls the passed continuation with the evaluated value instead of returning the result directly Such style of passing the result is called Continuation Passing Style CPS Direct style of passing the result function getFoo Foo CPS stylefunction getFooCPS lt A gt cont foo Foo gt A А CPS is rarely found immediately in the software source code Compilers are one of the main areas of its application as the intermediate format before generating the machine code Code conversion to CPS allows transforming recursive function calls to tail recursion that can be easily optimized to avoid stack growth during evaluations Continuations are a very powerful tool that can be used to implement control structures such as early function exit explicit call for tail recursion imperative cycles etc For more details on the use of continuations see the example for the Scheme language here Futures and promisesFutures Promises or Deferred are a construct containing the evaluation of asynchronous value They emerged in functional programming as a tool used to simplify parallel evaluations and execute queries in distributed systems const getJson url gt fetch url then resp gt resp json Sending serial queriesconst getUserInfo getJson current user id then userId gt getJson user info userId then userInfo gt console log Hi userInfo firstName your id is userId Promises were popularized mainly because of their adaptation and extensive use in the browser JavaScript execution in the browser is limited by only one execution thread so blocking while waiting for an HTTP response as is the case with most platforms would have led to the page hangup and annoy users This is why callback functions are used to process responses to HTTP queries in the browser At the same time it s not very convenient to combine such requests and the term “Callback Hell came up to describe the code that has become illegible due to a large number of callbacks Promises have allowed partially solving the issue of sending parallel queries and serial query chains Sending parallel queriesconst fetchInParralel Promise all getJson current user info getJson shopping cart getJson recently viewed items then userInfo cart viewedItems gt Display the page using the data sent from the server In many popular languages such as C Java JavaScript promises have become the main tool for asynchronous programming Monadic interfaceThe names of many constructs and programming techniques in Haskell were borrowed from category theory and other branches of mathematics One of such terms the Monad has become the object of many memes and jokes about functional programming There are lots of posts on the Web explaining what “Monads are in functional languages and how to use them To put it simply “monad is just an interface with two methods that allow combining evaluations into a chain in the same way it s done in the promise chain example The promises themselves also illustrate the monadic interface implementation Example of a monad used to generate pseudo random values parameter Аis the type of generated valueclass Random lt A gt Creation of Random using a random valueе static of lt A gt value A Random lt A gt Method used to implement the call chain chain lt A B gt this Random lt A gt then a A gt Random lt B gt Random lt B gt declare function randomNumber min number max number Random lt number gt declare const randomString Random lt string gt Example of using the monad chainconst randomUser Random lt User gt randomString chain userName gt randomNumber chain userAge gt Random of name userName age userAge Among other applications of monads in purely functional languages such as Haskell is the side effect encapsulation As it s not possible to make a database query read a file or even print a line in the standard output in these languages by calling ordinary functions monads are used to perform these actions At the same time their application goes beyond side effects the monadic interface is universal and allows writing generic laconic high level code which is why the monads are used everywhere in Haskell Beyond Haskell monads themselves are not so widely used but their influence can be seen primarily in programming using promises and in the async await construct which we ll talk about below AsyncGetting back to the examples of code with promises you can notice that despite all advantages of the promises the call chain looks no better than callbacks The async await syntactic structure allows taking it a step further and improving the code with the promise chain turning it into something much like the code with blocking calls const getJson url gt fetch url then resp gt resp json Sending serial queriesasync function getUserInfo const userId await getJson current user id const userInfo await getJson user info userId console log Hi userInfo firstName your id is userId The emergence of async await can be traced back to the researches devoted to functional programming in Haskell and ML which gave rise to the async workflows in F and then C ConclusionsProgramming languages move on and develop actively accumulating new ever more advanced and convenient tools As you can see such popular languages as Python or С are acquiring a growing number of features originating from functional programming More recent languages such as Scala or Kotlin support functional tools from the very beginning It turns out that functional programming is much closer than might appear at first sight even if you develop in C or Java We d be happy to learn about your experience with these or any other functional tricks in your day to day development	2021-11-15 14:30:19
