ReactJS started as a tool for a Facebook developer and grew into one of the most popular JavaScript libraries out there. Find out more about the history of this important technology in the latest BairesDev article.
When he was a software engineer at Facebook in 2010, Jordan Walke created the popular JavaScript library ReactJS to help make his own job easier. Walke initially built the library when he was working on the Ads section of the popular social media platform and needed a way to update specific parts of a page without having to refresh the entire thing. To accomplish this, he created the FaxJS prototype, which he then integrated with XHP in 2011 to create the first rough version of ReactJS. Since then, the library has become one of the most widely used and influential libraries in the web development industry to date.
ReactJS gained immense popularity among web developers due to its unique approach to building web applications. It uses declarative syntax, which allows developers to describe what they want the UI to look like rather than how to get there. This approach is different from traditional JavaScript libraries that use imperative syntax and require developers to write out the steps necessary to achieve a certain outcome. ReactJS also uses a virtual DOM. This allows devs to update only the parts of the UI that need changing instead of having to update the entire page, which makes ReactJS fast and efficient for handling complex and dynamic user interfaces.
ReactJS features a large and active community of developers who contribute to the library and create third-party tools and plugins, such as Redux, React Native, and Next.js. Developers also introduced ReactJS Hooks in 2019. This enabled them to write reusable logic that’s shareable across components. The shareability makes it easier for devs to build and maintain complex applications.
Over the years, ReactJS has become more accessible to a wider audience, thanks to tools like Create ReactJS App. This tool allows developers to create a ReactJS project with just a few simple commands to make it easier for beginners to get started with the library and contribute to the growth of the ReactJS developer community.
ReactJS continues to evolve and improve, and as it does, it will undoubtedly remain a popular choice among web developers. Its unique approach to building web applications, combined with its ability to handle complex and dynamic user interfaces, and its large and active community of developers are just some of the reasons why ReactJS remains one of the most loved tools in the web development community.
