Fetch Data in React: Goodbye, useEffect hook 


From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. Thankfully, there is a science (well, math) to side effects, formalized in state machines and statecharts, that can help us visually model and understand how to declaratively orchestrate effects, no matter how complex they get. In this talk, we’ll ditch the useEffect hook and discover how these computer science principles can be used to simplify effects in our React apps.

Functional Programming Explained | The Essence of Functional Programming

Functional Programming Explained | The Essence of Functional Programmi

This tutorial dives into the origins of functional programming, going all the way back to where the term was first introduced, to see how it evolved over time into our modern understanding of what FP essentially involves.


What is Functional Programming?

Functional programming (also called FP) is a way of thinking about software construction by creating pure functions. It avoid concepts of shared state, mutable data observed in Object Oriented Programming.

Functional langauges empazies on expressions and declarations rather than execution of statements. Therefore, unlike other procedures which depend on a local or global state, value output in FP depends only on the arguments passed to the function.

In this tutorial, you will learn-

  • What is functional programming?
  • Characteristics of functional Programming
  • History of Functional programming
  • Functional Programming Languages
  • Basic Functional Programming Terminology and Concepts
  • The benefits of functional programming
  • Limitations of Functional Programming
  • Functional Programming vs. Object-oriented Programming

Characteristics of Functional Programming

  • Functional programming method focuses on results, not the process
  • Emphasis is on what is to be computed
  • Data is immutable
  • Functional programming Decompose the problem into ‘functions
  • It is built on the concept of mathematical functions which uses conditional expressions and recursion to do perform the calculation
  • It does not support iteration like loop statements and conditional statements like If-Else

History of Functional programming

  • The foundation for Functional Programming is Lambda Calculus. It was developed in the 1930s for the functional application, definition, and recursion
  • LISP was the first functional programming language. McCarthy designed it in 1960
  • In the late 70’s researchers at the University of Edinburgh defined the ML(Meta Language)
  • In the early 80’s Hope language adds algebraic data types for recursion and equational reasoning
  • In the year 2004 Innovation of Functional language ‘Scala.’

Functional Programming Languages

The objective of any FP language is to mimic the mathematical functions. However, the basic process of computation is different in functional programming.

Here, are some most prominent Functional programming languages:

  • Haskell
  • SML
  • Clojure
  • Scala
  • Erlang
  • Clean
  • F#
  • ML/OCaml Lisp / Scheme
  • XSLT
  • SQL
  • Mathematica

Basic Functional Programming Terminology and Concepts

Immutable Data

Immutable Data means that you should easily able to create data structures instead of modifying ones which is already exist.

Referential transparency

Functional programs should perform operations just like as if it is for the first time. So, you will know what may or may not have happened during the program’s execution, and its side effects. In FP term it is called Referential transparency.

Modularity

Modular design increases productivity. Small modules can be coded quickly and have a greater chance of re-use which surely leads to faster development of programs. Apart from it, the modules can be tested separately which helps you to reduce the time spent on unit testing and debugging.

Maintainability

Maintainability is a simple term which means FP programming is easier to maintain as you don’t need to worry about accidentally changing anything outside the given function.

First-class function

‘First-class function’ is a definition, attributed to programming language entities that have no restriction on their use. Therefore, first-class functions can appear anywhere in the program.

Closure

The closure is an inner function which can access variables of parent function’s, even after the parent function has executed.

Higher-order functions

Higher-order functions either take other functions as arguments or return them as results.

Higher-order functions allow partial applications or currying. This technique applies a function to its arguments one at a time, as each application returning a new function which accepts the next argument.

Pure function

A ‘Pure function’ is a function whose inputs are declared as inputs and none of them should be hidden. The outputs are also declared as outputs.

Pure functions act on their parameters. It is not efficient if not returning anything. Moreover, it offers the same output for the given parameters

Example:

Function Pure(a,b)
{
	return a+b;
}

Impure functions

Impure functions exactly in the opposite of pure. They have hidden inputs or output; it is called impure. Impure functions cannot be used or tested in isolation as they have dependencies.

Example

int z;
function notPure(){
	z = z+10;
}

Function Composition

Function composition is combining 2 or more functions to make a new one.

Shared States

Shared states is an importance concept in OOP programming. Basically, It’s adding properties to objects. For example, if a HardDisk is an Object, Storage Capacity and Disk Size can be added as properties.

Side Effects

Side effects are any state changes which occur outside of a called function. The biggest goal of any FP programming language is to minimize side effects, by separating them from the rest of the software code. In FP programming It is vital to take away side effects from the rest of your programming logic.

The benefits of functional programming

  • Allows you to avoid confusing problems and errors in the code
  • Easier to test and execute Unit testing and debug FP Code.
  • Parallel processing and concurrency
  • Hot code deployment and fault tolerance
  • Offers better modularity with a shorter code
  • Increased productivity of the developer
  • Supports Nested Functions
  • Functional Constructs like Lazy Map & Lists, etc.
  • Allows effective use of Lambda Calculus

Limitations of Functional Programming

  • Functional programming paradigm is not easy, so it is difficult to understand for the beginner
  • Hard to maintain as many objects evolve during the coding
  • Needs lots of mocking and extensive environmental setup
  • Re-use is very complicated and needs constantly refactoring
  • Objects may not represent the problem correctly

Functional Programming - Introduction

Functional programming languages are specially designed to handle symbolic computation and list processing applications. Functional programming is based on mathematical functions. Some of the popular functional programming languages include: Lisp, Python, Erlang, Haskell, Clojure, etc.

Functional programming languages are categorized into two groups, i.e. −

Pure Functional Languages − These types of functional languages support only the functional paradigms. For example − Haskell.

Impure Functional Languages − These types of functional languages support the functional paradigms and imperative style programming. For example − LISP.

Functional Programming – Characteristics

The most prominent characteristics of functional programming are as follows −

Functional programming languages are designed on the concept of mathematical functions that use conditional expressions and recursion to perform computation.

Functional programming supports higher-order functions and lazy evaluation features.

Functional programming languages don’t support flow Controls like loop statements and conditional statements like If-Else and Switch Statements. They directly use the functions and functional calls.

Like OOP, functional programming languages support popular concepts such as Abstraction, Encapsulation, Inheritance, and Polymorphism.

Functional Programming – Advantages

Functional programming offers the following advantages −

Bugs-Free Code − Functional programming does not support state, so there are no side-effect results and we can write error-free codes.

Efficient Parallel Programming − Functional programming languages have NO Mutable state, so there are no state-change issues. One can program "Functions" to work parallel as "instructions". Such codes support easy reusability and testability.

Efficiency − Functional programs consist of independent units that can run concurrently. As a result, such programs are more efficient.

Supports Nested Functions − Functional programming supports Nested Functions.

Lazy Evaluation − Functional programming supports Lazy Functional Constructs like Lazy Lists, Lazy Maps, etc.

As a downside, functional programming requires a large memory space. As it does not have state, you need to create new objects every time to perform actions.

Functional Programming is used in situations where we have to perform lots of different operations on the same set of data.

Lisp is used for artificial intelligence applications like Machine learning, language processing, Modeling of speech and vision, etc.

Embedded Lisp interpreters add programmability to some systems like Emacs.

Functional Programming vs. Object-oriented Programming

The following table highlights the major differences between functional programming and object-oriented programming −

Functional ProgrammingOOP
Uses Immutable data.Uses Mutable data.
Follows Declarative Programming Model.Follows Imperative Programming Model.
Focus is on: “What you are doing”Focus is on “How you are doing”
Supports Parallel ProgrammingNot suitable for Parallel Programming
Its functions have no-side effectsIts methods can produce serious side effects.
Flow Control is done using function calls & function calls with recursionFlow control is done using loops and conditional statements.
It uses "Recursion" concept to iterate Collection Data.It uses "Loop" concept to iterate Collection Data. For example: For-each loop in Java
Execution order of statements is not so important.Execution order of statements is very important.
Supports both "Abstraction over Data" and "Abstraction over Behavior".Supports only "Abstraction over Data".

Efficiency of a Program Code

The efficiency of a programming code is directly proportional to the algorithmic efficiency and the execution speed. Good efficiency ensures higher performance.

The factors that affect the efficiency of a program includes −

  • The speed of the machine
  • Compiler speed
  • Operating system
  • Choosing right Programming language
  • The way of data in a program is organized
  • Algorithm used to solve the problem

The efficiency of a programming language can be improved by performing the following tasks −

By removing unnecessary code or the code that goes to redundant processing.

By making use of optimal memory and nonvolatile storage

By making the use of reusable components wherever applicable.

By making the use of error & exception handling at all layers of program.

By creating programming code that ensures data integrity and consistency.

By developing the program code that's compliant with the design logic and flow.

An efficient programming code can reduce resource consumption and completion time as much as possible with minimum risk to the operating environment.


What is functional programming? A practical guide

Functional programming means using functions to the best effect for creating clean and maintainable software. This article illustrates the concepts behind the functional paradigm with practical examples in JavaScript and Java.

Functional programming has been a current in software development since the earliest days, but has taken on new importance in the modern era. This article looks at the concepts behind functional programming and offers a practical understanding with examples in JavaScript and Java.

Functional programming defined

Functions are fundamental to code organization; they exist in all higher order programming languages. Generally, functional programming means using functions to the best effect for creating clean and maintainable software. More specifically, functional programming is a set of approaches to coding, usually described as a programming paradigm.

Functional programming is sometimes defined in opposition to object-oriented programming (OOP) and procedural programming. That is misleading as these approaches are not mutually exclusive and most systems tend to use all three.

Functional programming offers clear benefits in certain cases, it’s used heavily in many languages and frameworks, and it’s prominent in current software trends. It is a useful and powerful tool that should be part of the conceptual and syntactic toolkit of every developer.

Pure functions

The ideal in functional programming is what is known as pure functions. A pure function is one whose results are dependent only upon the input parameters, and whose operation initiates no side effect, that is, makes no external impact besides the return value.

The beauty of a pure function is in its architectural simplicity. Because a pure function is reduced to only the arguments and return value (that is, its API), it can be seen as a complexity dead end: Its only interaction with the external system in which it operates is via the defined API.

This is in contrast to OOP where object methods are designed to interact with the state of the object (the object members) and in contrast to procedural style code where external state is often manipulated from within the function.

However, in actual practice, functions often end up needing to interact with the broader context, as evidenced by React's useEffect hook.

Immutability

Another tenet of functional programming philosophy is not to modify data outside the function. In practice, this means to avoid modifying the input arguments to a function. Instead, the return value of the function should reflect the work done. This is a way of avoiding side effects. It makes it easier to reason about the effects of the function as it operates within the larger system.

First class functions

Beyond the pure function ideal, in actual coding practice functional programming hinges on first class functions. A first class function is a function that is treated as a “thing in itself,” capable of standing alone and being treated independently. Functional programming seeks to take advantage of language support in using functions as variables, arguments, and return values to create elegant code.

Because first class functions are so flexible and useful, even strongly OOP languages like Java and C# have moved to incorporate first class function support. That is the impetus behind Java 8’ support for Lambda expressions.

Another way to describe first class functions is functions as data. That is to say, a first class function can be assigned to a variable like any other data. When you write let myFunc = function(){} you are using a function as data.

Higher-order functions

A function that accepts a function as an argument, or returns a function, is known as a higher-order function — a function that operates upon a function.

Both JavaScipt and Java have added improved function syntax in recent years. Java added the arrow operator and the double colon operator. JavaScript added the arrow operator. These operators are designed to make it easier to define and use functions, especially inline as anonymous functions. An anonymous function is one that is defined and used without being given a reference variable.

Functional programming example: Collections

Perhaps the most prominent example of where functional programming shines is in dealing with collections. This is because being able to apply chunks of functionality across the items in a collection is a natural fit to the pure function idea.

Consider Listing 1, which takes advantage of the JavaScript map() function to uppercase the letters in an array.

Listing 1. Using map() and an anonymous function in JavaScript

let letters = ["a", "b", "c"];
console.info( letters.map((x) => x.toUpperCase()) ); // outputs ["A", "B", "C"]

The beauty of this syntax is that the code is tightly focused. No imperative plumbing, such as a loop and array manipulation, is required. The thought process of what is being done is cleanly expressed by this code.

The same thing is achieved with Java’s arrow operator as seen in Listing 2.

Listing 2. Using map() and an anonymous function in Java

import java.util.*; 
import java.util.stream.Collectors;
import static java.util.stream.Collectors.toList;
//...
List lower = Arrays.asList("a","b","c");
System.out.println(lower.stream().map(s -> s.toUpperCase()).collect(toList())); // outputs ["A", "B", "C"]

Listing 2 makes use of Java 8’s stream library to perform the same task of upper-casing a list of letters. Notice that the core arrow operator syntax is virtually identical to JavaScript, and they do the same thing, i.e., create a function that accepts arguments, performs logic, and returns a value. (It’s important to note that if the function body thus defined lacks braces around it, then the return value is automatically given.)

Continuing with Java, consider the double colon operator in Listing 3. This operator allows you to reference a method on a class: in this case, the toUpperCase method on the String class. Listing 3 does the same thing as Listing 2. The different syntaxes come in handy for different scenarios.

Listing 3. Java Double Colon Operator

// ...
List upper = lower.stream().map(String::toUpperCase).collect(toList());

In all three examples above, you can see that higher-order functions are at work. The map() function in both languages accepts a function as the argument.

Put another way, you could look at the passing of functions into other functions (in the Array API or otherwise) as functional interfaces. The provider functions (which consume the parameter functions) are plug-ins to generalized logic.

This looks a lot like a strategy pattern in OOP (and indeed, in Java, an interface with a single method is generated under the hood) but the compactness of a function makes for a very tight component protocol.

As another example, consider Listing 4, which defines a route handler in the Express framework for Node.js.

Listing 4. Functional route handler in Express

var express = require('express');
var app = express();
app.get('/', function (req, res) {
  res.send('One Love!');
});

Listing 4 is a fine example of functional programming in that it allows for the clean definition of exactly what is required for mapping a route and handling requests and responses — although it might be argued that manipulating the response object within the function body is a side effect.

Curried functions

Now consider the functional programming notion of functions that return functions. This is less commonly encountered than functions as arguments. Listing 5 has an example from a common React pattern, where the fat-arrow syntax is chained.

Listing 5. A curried function in React

handleChange = field => e => {
e.preventDefault();
// Handle event
}

The purpose of the above is to create an event handler that will accept the field in question, and then the event. This is useful because you can apply the same handleChange to multiple fields. In short, the same handler is usable on multiple fields.

Listing 5 is an example of a curried function. “Curried function” is a bit of a frustrating name. It honors a person, which is nice, but it doesn’t describe the concept, which is confusing. In any case, the idea is that when you have functions that return functions, you can chain together calls to them, in a more flexible way than creating a single function with multiple arguments.

When calling these kinds of functions, you will encounter the distinctive “chained parentheses” syntax: handleChange(field)(event).

Programming in the large

The preceding examples offer a hands-on understanding of functional programming in a focused context, but functional programming is intended to drive greater benefits to programming in the large. Put another way, functional programming is intended to create cleaner, more resilient, large-scale systems.

It’s hard to provide examples of this, but one real-world instance is React’s move to promote functional components. The React team has noted that the more concise functional style of component offers benefits that compound as interface architecture grows larger.

Another system that makes use of functional programming heavily is ReactiveX. Large-scale systems built on the kind of event streams that ReactiveX uses can benefit from decoupled software component interaction. Angular fully adopts ReactiveX (RxJS) across the board as an acknowledgment of this power.

Variable scope and context

Finally, an issue that is not necessarily part of functional programming as a paradigm, but is very important to pay attention to when doing functional programming, is that of variable scope and context.

In JavaScript, context specifically means what the this keyword resolves to. In the case of the JavaScript arrow operator, this refers to the enclosing context. A function defined with the traditional syntax receives its own context. Event handlers on DOM objects can take advantage of this fact to ensure that the this keyword refers to the element being handled.

Scope refers to the variable horizon, that is, what variables are visible. In the case of all JavaScript functions (both fat-arrow and traditional) and in the case of Java’s arrow-defined anonymous functions, the scope is that of the enclosing function body—although in Java, only those variables that are effectively final can be accessed. This is why such functions are referred to as closures. The term means the function is enclosed within its containing scope.

This is important to remember: Such anonymous functions have full access to the variables in scope. The inner function can operate against the outer function’s variables. This could be considered a non-pure function side effect.
