Is React JS a server side or a client side script? This is a question that is now on many web developers’ minds as they consider the best framework for their development project. React JS is an increasingly popular open-source JavaScript library for building large, complex user interfaces. While React has made a huge impact on how users interact with the web, there is still confusion about which side of the web development it belongs to. To understand the issue fully, it’s important to take a look at the core concepts behind React JS and why it has become the go-to solution for web application development projects.
To begin, what is the difference between client-side and server-side scripting? On the web, client-side scripting is code that is executed on the user’s machine, while server-side scripting is code that is executed on the server. In short, client-side scripting is more for presentation, while server-side scripting is more for application logic. React JS is a library that sits atop the core JavaScript language, which is executed in the browser. So the main question here: does it belong on the client-side or the server-side?
There are some opinions suggesting that React is more of a client-side framework than a server-side language. After all, it does execute snippets of JavaScript that are served to the client. But then there are also some who argue that React should be classified as a server-side technology, since it enables developers to create application logic that is executed on the server. So, which is the correct view?
In this article, you will learn more about React JS and the pros and cons of its server-side versus client-side implementation. We’ll look at the debate over the differences between the two, and explore the various use cases that are better suited to each approach. Lastly, we’ll consider whether React JS is truly a server-side framework or if it’s more accurately considered a client-side technology. Whether or not you agree, the debate over server-side versus client-side programming will continue on as more development teams look for the best tool for their projects.


React JS is an open source JavaScript library. It was created by Facebook and is primarily used to develop user interface components for web applications. It is also used for creating single-page applications (SPAs) and cross-platform mobile applications. React is sometimes referred to as a “framework”, but it is not a complete development stack in the way that frameworks like Angular or Vue are.
Server side scripting language describes a programming language that runs on a remote web server and produces the pages that a web browser requests. The most common server side scripting language is PHP, but there are others, including Javascript, ASP.NET, and Ruby.
Client side scripting language, on the other hand, is a computer programming language that runs within a web browser or other application (such as Adobe Flash). Examples of client side scripting languages include HTML, CSS, and JavaScript.
React is a client side scripting language, which means that it runs directly in the web browser and produces the visual elements of the website. React specializes in creating user interface elements for single-page applications (SPAs) and cross-platform mobile applications. React components are written using an extension of JavaScript called JSX, which allows for the inclusion of HTML and CSS. React components are accompanied by a specialized type of JavaScript code known as state, which helps the components respond and interact with user input.

What is React JS?

React JS is an open source JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies. React allows developers to create large web applications that use data and can change over time without reloading the page. It aims primarily to provide speed, simplicity, and scalability.

Benefits of React JS

React JS offers many advantages, including:

  • Improved user experience
  • Easy to learn and use
  • Reduced development time and cost
  • Enhanced scalability and performance

Applications of React JS

React JS is used for creating interactive user interfaces for both web and mobile applications. It is used for large scale applications such as Facebook and Instagram, and for smaller applications such as sites that have complex menus and navigation. React is also being used to create virtual reality (VR) applications.
React is great for creating interactive user experiences and is becoming increasingly popular due to its many benefits. It is easy to learn and use, and its scalability means that applications can be built quickly with less cost.

How does React JS work?

What is React JS?

React (also known as React.js or ReactJS) is a JavaScript library created by Facebook Inc. for building user interfaces for both web and mobile applications. It is also used for creating single page applications. React was designed to provide the simplicity and speed of the web with the power and responsiveness of a modern UI design system. It can be used for both client-side and server-side development.

How Does React JS Work?

React is based on a virtual DOM (document object model), which makes it fast and efficient compared to traditional web pages. The virtual DOM is a representation of the web page, not the actual DOM. With React, when something in the view needs to change, the developer can simply change the virtual DOM object and React will update the actual DOM tree to reflect the changes. This makes React incredibly fast to develop and maintain, as it requires fewer steps and resources than traditional web pages.
React also enforces a “one-directional” data flow from the parent component to the child components. This means that parent components can send data to children components, but children can never send data back to the parent unless explicitly allowed to do so. This method ensures consistent data flow and allows developers to track and troubleshoot when issues arise.
React uses components to break up the user interface into smaller, reusable chunks. This helps to make larger projects more manageable and allows components to be shared across several projects. React also makes it easy to create complex user interfaces with dynamic behavior, such as autocomplete forms and complex navigation menus.
React also helps to increase performance by improving the speed and responsiveness of the user interface. It does this by reducing the number of DOM manipulations by ensuring that only components that need to be updated are updated, and optimizing the way the components process data.
React is highly popular among developers due to its simplicity, scalability, and flexibility. It takes time and investment to become proficient with React, but the results are incredibly rewarding and can have an immense impact on the user experience.

Additionally, React JS introduces a component-based approach of developing JavaScript applications, allowing developers to create components that can be re-used in multiple applications.

Benefits of using React JS

One of the advantages of React JS is its intuitive syntax and syntax extension, JSX. This allows for writing components quickly in a clearly organized way. React JS also offers improved performance due to its use of virtual DOM which allows for element updates to be batched and processed all at once instead of having to be handled individually. Furthermore, as React JS is built on components, it is easy to debug, modify or add new components to existing ones. Additionally, React JS is popular due to its lightweightness and ability to render on the server, as well as its scalability that allows for the development of applications for any device size.
The use of React JS also brings many more benefits such as its open-source nature allowing for its extensive adoption through the network, its efficient data binding model and its wide range of available tools and resources. This technology also offers speed, resulting as improvements to loading time for web applications as well as improved data fetching on mobile devices. In addition, React JS also offers high-quality code coupled with high flexibility allowing for the rapid development of complex applications. Finally, a few of its other notable advantages are its extensive Eco-system and its integration with other frameworks such as Redux and GraphQL.
