What is React.js Used For? Top 10 Examples
What is React.js?
React.js is a widely popular JavaScript library that is mainly used for building dynamic single-page and multi-page web interfaces. Its flexible and scalable nature has made it one of the most in-demand technologies in the programming world. This makes the user experience smoother and more responsive. React JS is used for web application development, whereas React Native is designed for developing mobile applications on iOS and Android platforms. Many developers complement React with Material a popular component library that helps build user interfaces following best practices, ensuring a seamless experience for users.
Though React is often mistaken to be a framework or a language, it's actually a library. With the help of React, web application developers can develop high-traffic web applications that handle dynamic data without page reloads. Its prime objectives are scalability, simplicity, and speed. React only focuses on the user interface, so it remains light and streamlined. Let's discuss what React. js is used for, and also why it's the backbone of the majority of high-end applications with the top 10 examples.
Key Features of React.js
- Productivity: Component-based architecture in React enables developers to build reusable UI components. It saves time on development, boosts productivity, and makes it simple to build scalable apps.
- SEO and UX Friendliness: Fast rendering of React is important for both UX and SEO. Google's emphasis on Core Web Vitals has ensured React provides fast load performance and smooth interaction, which is good for SEO ranking and user satisfaction.
- Solid Support: React has a solid community and tech giant support behind it. This extensive support has flattened its learning curve, and it is offering developers resources to enhance their skills.

Top 10 Examples of React.js Applications
Following are the top examples wherein React.js powers dynamic, high-performance applications:
Being the origin of React, Facebook makes extensive use of this library on its platform. React drives much of the functionality in the Facebook web interface, which makes the site dynamic and responsive.
Instagram, which is also owned by Facebook, uses React for several functionalities, such as geolocation capabilities and search engines. Instagram also switched to React Native in 2016 to speed up mobile development for iOS and Android.
Dropbox
Dropbox used React due to its capability to improve user experience, especially enhancing file load time and file size. The performance advantages of React are important in cloud storage platforms where efficiency and speed are significant.
Pinterest
Pinterest uses React to deliver an interactive, visually rich user experience.
Discord
Discord, originally a gaming communication platform, uses React for almost 98% of its codebase.
The library’s flexibility and performance help create a seamless and interactive user experience for its global user base.
Netflix
Netflix takes advantage of React's component-based design to reuse UI components that deliver consistent performance and code maintenance ease. The virtual DOM in React optimizes rendering, something critical for the content-intensive Netflix platform, for a seamless viewing experience on various devices.
The New York Times
React helps the New York Times by providing an interactive, engaging user experience on its website. With React, the site makes sure its content is loaded in seconds and still very interactive, a fundamental aspect of maintaining readers' interest. They also created a standalone app, The Red Carpet Project, with nothing but React.
Airbnb
Airbnb uses React to build a complex and very responsive user interface. The dedication of the platform to React is not just reflected in its extensive usage but also in its contribution to the React community, including the Airbnb React/JSX Style Guide, which has become an essential resource for React developers.
Reddit applies React to build its front-end user interface to enable responsive discussion and content-sharing platforms. React's rendering efficiency supports Reddit in handling large volumes of users without slowing down, even when content is being continuously updated.
PayPal
PayPal applies React to integrate payment systems within its platform seamlessly. Official React components have been created by the company to facilitate embedding PayPal's checkout functionality within applications developed using React.
Potential Disadvantages of React.js
Though React is extremely useful, it does have a few drawbacks:
- Steep Learning Curve for Newcomers: React demands a good knowledge of JavaScript and contemporary development techniques. Its flexibility requires developers to have the experience to use all its features to the fullest.
- Complexity for Big Applications: As applications using React become large, handling state and props among different components becomes complicated without architectural planning.
Why Use React.js?
- Performance: React Virtual DOM improves the UI rendering and updates improving performance in apps by minimizing direct interactions with the real DOM. The user experience is more seamless even with data-driven or dynamic applications.
- Reusability: The component-based design of React makes it possible to create reusable UI components. They can be used in other projects or project sub-divisions, saving time and facilitating maintenance.
- Massive Community: React has a very large and growing community, providing a wealth of resources, tutorials, libraries, and tools. This allows developers to be able to solve common problems and keep up with the best and latest trends and best practices.
- Cross-Platform Development: It allows developers to take advantage of the strength of React in mobile app development such that they can develop native Android and iOS apps from a common codebase. It facilitates cross-platform app development with greater ease without compromising performance.
summary
Its component-based architecture, flexibility, speed, scalability, and strong developer community make it an ideal choice for both large and small projects. While it does require skill to learn, the widespread business acceptance of React by large players like Facebook, Netflix, and Airbnb is a piece of evidence to the fact that its advantages outweigh the challenges. Whether you are developing an e-commerce website, social networking website, or business application, React.js offers you the facilities and assistance to create a spectacular user experience.
