React was designed to create sophisticated user interfaces using a very simple and clear syntax. It allows developers to build reusable components, write less code for UI implementation, and achieve better performance and stability. It’s also highly scalable, allowing engineers to build web applications of any size. Additionally, React is extremely SEO friendly and is ideal for websites requiring lightning-fast loading, such as eCommerce sites with thousands of products or real estate portals with interactive maps, filters, and dynamic content.
The most popular use case for React is developing applications with a large amount of data and changing it often. To keep the application fast, React uses a virtual DOM (Document Object Model). The virtual DOM is a copy of the actual DOM, and every time there is a change in the data state, React will update the virtual DOM first. It then compares the virtual DOM to the actual DOM and figures out which parts of the page have changed. Then, React will figure out the least expensive way to patch the changes in the real DOM without rendering it again. This approach avoids layout trashing and significantly improves performance.
React is also a great tool for creating complex user interfaces with many components, as it makes it easy to manage changes and the relationship between data and what appears on the screen. In comparison, jQuery can be challenging for such tasks due to its heavy and slow memory footprint.
One of the main reasons React is so popular is its ability to debug quickly and efficiently. The React framework uses unidirectional data flow, making it easier to track and debug errors. Additionally, React JS uses a virtual DOM, which is a lightweight copy of the real DOM, and this enables faster rendering and loading of web pages.
React also enables developers to create more structured and organized codebases. This is particularly beneficial for teams that have to deal with large-scale projects and numerous components, states, and data flows. It’s no surprise that React is a great choice for forums, job boards, e-learning sites, and any other platform that
requires high levels of interaction between users.
React has become an indispensable tool for thousands of companies, including some Fortune 500 brands, like PayPal, Netflix, Tencent QQ, and Airbnb. In addition to providing a rich library of ready-made UI components, React has helped them achieve lightning-fast load times and better search engine optimization. As a result, they have seen an increase in traffic and sales. Moreover, React can be used to develop both web and mobile apps.
