In 2011, as the user base of Facebook surged, the company's engineers encountered performance challenges with their news feed. To address this, they embarked on developing a solution that would revolutionize web development. Thus, React.js was born. Initially used for Facebook's internal projects, React.js soon garnered attention for its efficiency and was open-sourced for the world to benefit.

Popularity and Adoption

Fast forward to today, React.js is one of the most used JavaScript libraries in front-end development. It is used in the dynamic UI development. You can learn more about ReactJS's key features and use cases here. 

As per a report by Statista, It was the second most used JavaScript-based front-end development technology in 2023, overtaking jQuery, with 42% of developers reported to be using it.

  • As of 2024, it has over 221k stars on GitHub and over 1500 contributors. This huge community plays a crucial role in its evolution.

  • It powers over 14 million applications across the globe. This number also includes some of the biggest and most influential tech giants. (BuiltWith, 2024).

Why Reactjs?

ReactJS development allows developers to build interactive, responsive web applications with reusable components. This is why it is hailed as one of the most powerful JavaScript libraries in the current era for developing modern web applications. Several factors made it a popular JavaScript library. Below are a few of them:

Declarative:  Since it is declarative, it provides a very simple way to develop interactive user interfaces.

Reusable components: The components we code using React.js can be reused, thus breaking complex logic into multiple smaller parts.

Virtual DOM: With react, we usually communicate with the virtual DOM (a copy of DOM saved in memory), which improves the application’s performance as it works by activating the individual component on the virtual DOM instead of reloading the whole page.

React.js is easy to grasp: Nowadays, simplicity and the learning curve are significant factors behind programming language growth.

A great number of pre-built libraries: It has so many pre-built libraries that can speed up development time.

Strong community support: React has a huge community of developers, so you can collaborate and get help from supporters around the world.

Top 10 Websites using ReactJS

ReactJS established itself as a dominant force in front-end development, evidenced by its extensive adoption among industry leaders like Facebook and Netflix. 

These companies leverage React’s component-based architecture to create dynamic and user-centric application UIs.  With over 14 million websites built with React, it is a mature, popular technology.

1. Facebook

Facebook is the world’s largest social platform, boasting over 2.9 billion users. It leverages ReactJS alongside other technologies for its web application. Interestingly, ReactJS was developed by Jordan Walke, a software engineer at Facebook, and subsequently integrated into the Facebook web application.

By integrating ReactJS, Facebook has improved user experience and introduced more interactive features. This move has eliminated the traditional news feed, which previously required the page to reload every time users interacted with in-page elements.

2. Instagram

Instagram is one of the most popular social media platforms, facilitating photo and video sharing while connecting millions of users worldwide.

Similar to Facebook, Instagram has also utilized ReactJS in its front-end development. React, alongside Backbone.Router, forms the backbone of Instragram's web page. Notably, features such as geolocation services, integration with Google Maps APIs, and precise search functionality highlight the extensive utilization within Instagram's framework. 

3. Netflix

Netflix is a subscription-based streaming service that lets users watch TV shows and movies. It features a clean, uncluttered homepage and a well-designed UI.

Netflix Likes React!, This blog gives detail on why the world’s leading streaming entertainment service provider adopted ReactJS.

In a blog post, Netflix revealed why they chose to adopt ReactJS:

We were able to leverage the following features to improve our application’s initial load times, runtime performance, and overall scalability – Netflix development team.

In its blog post, the company stats that it used ReactJS to improve application startup load time, runtime performance, and modularity . The world’s leading streaming service provider significantly improved the application startup load time, runtime performance, and modularity by using ReactJS.

4. Asana

Asana is a popular project management tool that helps individuals and teams to keep track of tasks. Its legacy framework (Luna1) was difficult to maintain and lacked these benefits. This resulted in a poor user experience as the tours were not very engaging.

The FX team Asana leveraged ReactJS to make first-time visitors' experience flawless. React offered a more stable and performant environment, allowing the FX team to create more interactive and effective product tours (Coachmarks) that users were more likely to complete.

In the blog published by Asana in 2018, they described how the company leveraged ReactJS development to build a high-performance web application that enhanced the first-time visitor experience.

5. Salesforce

Salesforce is the world’s leading customer relationship management (CRM) platform that offers cloud-based solutions to millions of businesses across the globe. It helps marketing, sales, commerce, service, and IT teams to connect, create and manage sales and marketing campaigns.

Visualforce is a framework, developed by Salesforce, that allows developers to build custom user interfaces. With the goal of enhancing user experience, Salesforce used ReactJs to speed up rendering for Visualforce pages and greatly benefited from the use of the React.JS library with its incorporation into this platform.

6. The New York Times

The development team at the New York Times was dealing with multiple codebases written in different languages for desktop, mobile and other products. This made it difficult to maintain and develop new features.

With React and Relay, they can create a single system for managing UI components and fetching data from various sources using GraphQL. This makes development faster and more efficient.

7. Dropbox (HelloSign)

Dropbox is a popular file hosting service that lets you store and share files online. It also features some amazing in-built features, such as HelloSign, an innovative solution that lets you sign documents within the app.

With the existing tech stack, the Dropbox team encountered a problem where the files supported for the signing were not opening in many browsers. Also, the team realized that it was time to adopt new technology that could help improve fidelity between the editor and increase the application performance and the editor’s usability.

Subsequently, the team decided to overhaul the signer with React. The decision to shift from Jquery to ReactJs first appeared to be quite daunting; nevertheless, it turned out to be fruitful, as it led to a substantial enhancement in HelloSign's functionality and performance, taking it to the next level.

8. Yahoo Mail

Yahoo mail has been around us for the past two decades. In early 2017, Yahoo mail got a new rich interface made upon switching their old tech stack that included libraries such as KnockOut, Durandal, and Rivets and embracing React.JS + Flux to improve the old bland user interface for developing a next-gen user-friendly and dynamic interface.

9. Instacart

Instacart is another popular platform built using React.JS. It is a popular website that allows customers to order from a particular store through a website and app and get the goods delivered online. With time when its customer base and partners grew many times, that made the company switched from Backbone, jQuery, Underscore, andHaml to ReactJS in order to improve its performance.

10. Reddit

Reddit is hailed as the “front page of the internet” that allows users from all over the world to connect with each other, engage in discussions or ask for help with a specific problem. According to a report by Reddit’s former senior software team lead – the platform started using React back in 2014. Also, a significant amount of front-end elements on the website are designed using React.JS.
