Web development is one of the most important aspects for making your business exceptional in the current age of digitalization. There is always a need to identify appropriate tools and frameworks for developing a user-friendly, scalable, and functional application, especially for a company in the growth stage.
One of the most common technologies, in this case, is the one that has been adopted by developers these days, and they can’t help it. That is ReactJS.
But what is React JS? What role has it played in the dynamic development that has taken over web designing? This blog is about React JS, its characteristics, and benefits for beginner and experienced developers.
What is React JS?
We all know Facebook created React JS. React JS, which also goes commonly by the name of React, is an open-source JavaScript library. Its purpose is to help us design amazing user interfaces, especially for single-page websites (they require a responsive and interactive UI experience).
Since 2013, React has revolutionized web development with its component-based structure, making it much easier to build intricate UI structures using reusable components.
It focuses on developing encapsulated components that manage their own state and can be combined to form sophisticated user interfaces. React provides fast and seamless user interactions by efficiently updating and rendering components as data changes.
History of React.js
The reason for developing ReactJs was the need for more interactive and real-time features in web applications.
In 2013, a software engineer at Facebook named Jordan Walke developed ReactJs. The component-oriented design and virtual DOM of React helped to manage multiple complex user interfaces. It did not take long for ReactJs to become popular due to its significantly improved performance report.
It also received help from a dedicated developer’s community and constant updates, like the introduction of Hooks in 2018, which put ReactJs at the summit of all technologies used to create contemporary websites.
Why do we need React JS for Web Development?
Previously, building web applications, especially in the front end, required frequent interaction with the DOM, an activity that was frustrating and made many mistakes.
This is not the case with React, due to the presence of a virtual DOM. The virtual DOM is an abstract representation of the actual DOM.
When looking at a scenario where an information update is needed, let’s say a modification made on a property of one of the components, React will first update the virtual DOM. It will only then compare and update the changes on the real DOM.
This leads to enhanced performance while at the same time addressing the needs of the users.
Furthermore, the component-oriented structure of React makes the development of UI easier, as the UI components can be created and used multiple times, thus enhancing the reusability of codes.
This disintegration leads to better structured and readable codes, thus easing the maintenance and expansion of web applications.
Features of React JS Framework
When it comes to web development, React has several features that make it a great choice:
Component-Based Architecture
This is the cardinal feature of React, which is the component-based architecture. Simply put, developers can create self-contained components that contain all of their logic and state. These components can be used easily in other parts of the application.
Virtual DOM
The virtual DOM serves as an abstract version of the actual DOM and is extensively used by React to ensure that the right updates are made to the UI components in correspondence to the changing data.
Declarative Syntax
React’s declarative syntax enables developers to easily specify the appearance of the UI based on a particular state, enhancing the application’s clarity and simplifying the debugging process.
Unidirectional Data Flow
React enforces a one-way data flow. In this way, data is passed from parent to child components, thus helping to make clear how changes to the data will result in changes in the UI and how these changes will be managed.
JSX (JavaScript XML)
JSX is an additional syntax written in XML that allows the author to mix HTML code together with JavaScript code, thereby enhancing the process of designing and arranging user interface elements.
Hooks
With the launch of React 16.8, React Hooks was introduced. This lets the developers use a range of functionalities, from states to the use of other properties inside React, without the need for class components. These hooks aid in the management of the states and side effects more neatly than other approaches and enhance the understandability and maintainability of the code
Components of React
React applications are made with the help of 2 components: functional and class. These are the building blocks of UI. Let us take a look at the two major components of React.
1. Functional Components
These functions are written in JavaScript in a very simple way. They take props as input and return React elements. Functional components display content on the screen, which makes testing and debugging easy.
Now with Hooks embracing React 16.8, functional components bear state and lifecycle as class components used to before. Only classes could do this.
2. Class Components
ES6 classes extend ‘React. Component’ and require a render method that returns a React element. Class components manage the state and the lifecycle methods. The hooks have gained attention for their effectiveness and precision in dealing with states and effects most efficiently.
But this is not the end of the story. These two components are further divided into 2 more components.
Stateful Components: These components track their internal state. Whenever there is a user action or other types of changes, they change their state and re-render themselves. In short, stateful components are very crucial when it comes to managing changing data and user interactivity.
Stateless Components: Do you know about presentational components? They do not manage any internal state but depend on the parent’s properties. They are generally used for showing display elements with respect to the props passed to them.
In React, it is possible to build components inside other components, increasing the hierarchy. This promotes reusability, allowing for easy maintenance, testing, management, and scaling of the applications.
Dividing the user interface into smaller, self-contained, and usable components allows developers to construct applications that are less cumbersome to manage and more efficient. So go ahead and start creating nested components in React for your own good!
Even after learning all the features and components of React, a question remains: What is the whole point of using React? Or how can React benefit us? So now read further to learn about the benefits React gives us.
How to create a website in React JS?
To start building a website with React JS, you will have to start by installing the required software, which includes Node.js and npm.
Then, to get your project started, run npx create-react-app my-website in the terminal. This command will create a new folder that contains the necessary files and other dependencies to start the project.
Use cd my-website to navigate to this folder, and npm start to run the development server.
Now kickstart your development functionality and create components that are coded in JSX, as those are the essential parts of building a React project.
In order to display changeable content, include styling via CSS or styled components and operation of states and props.
Improve your pages with external libraries such as React Router for page navigation and Redux for state management.
When everything on your website is done, then use npm run to make a production version of the site.
Some benefits of React JS
React JS presents several advantages for web development undertakings.
Virtual DOM includes a few processes of optimization, rendering, and stripping down interactions with the physical DOM; the performance is significantly better. With its component-based structure, React allows developers to develop UI elements that are reusable and, thereby, simplifies the management of the code and fosters uniformity of the sad app.
Being declarative makes it easier to write maintainable code, as a developer can declare what the UI should look like in any particular state. This feature guarantees a unidirectional flow of data, thereby making it simple to comprehend and troubleshoot the application.
React has a huge and vibrant robe of users who assist in the ecosystem by providing a number of resources, libraries, and even third-party tools that will speed up development. The ecosystem is highly extensive and provides numerous capabilities, such as a React Router for navigation and state management using Redux.
Online tools (including Next.js) allow operating server-side rendering capabilities in React. This is important for establishing a good SEO strategy that makes it possible for search engines to crawl and index the content created with React.
Also, it would be quite difficult to spot a technology that does not play nice with React, which adds to its versatility in engaging different technologies within a project.
Examples of React JS-Used Projects
Examples are the best way to understand a product. React JS has shown its usefulness through various examples.
Facebook developed React and employs it throughout the organization’s user interface to demonstrate the versatility of highly complex and dynamic applications.

React JS disadvantages
While React JS has many great benefits, it does come with a few drawbacks. For beginners, the learning curve can be a bit tough, especially when diving into things like JSX and hooks. The React ecosystem is always changing, with constant updates and new features to keep up with, which can be a little overwhelming at times. For smaller projects, using simpler libraries or frameworks might be a better fit to avoid unnecessary overhead. Setting up server-side rendering for SEO can be a bit tricky and might require some extra tools and know-how. With so many tools and libraries in the React ecosystem, it’s easy to feel overwhelmed by all the choices, but don’t worry; you’ll find the right ones for your needs with a little exploration and learning.
