What is React

React is a JavaScript library used to create user interfaces for various types of applications. It is available on an open source basis to a wide range of recipients. React therefore gives you the opportunity to create a very complex interface consisting of small, separate elements. React was created to simplify the process of overall interface building and to provide users with greater convenience when using the application. The React library uses an innovative way of rendering web pages, making them more dynamic. It is convenient both for the programmer (its creator) and for the final recipient of the application, i.e. its user.

React allows you to work and see any changes occurring on the interface in real time, which in turn makes it easier to work with objects. This is thanks to the use of the Virtual DOM virtual domain, where all changes are updated on an ongoing basis. React-based solutions include:

  • configurator applications whose interface is no different from applications installed independently on Windows years ago, e.g. Excel online or Word online,
  • store applications whose interface is independent of the backend and whose store has an API exposed, needing to replace its visual layer with a more attractive one,
  • dashboards and data visualizations,
  • administration panels,
  • realtime applications using and continuous communication with the server and interface updates.


  • The large number of active developers contributed to the sudden increase in React’s popularity. Thanks to Facebook’s support, many people from all over the world can contribute to the development of this tool.
  • React comes with many reusable components, which speeds up the product development process. Thanks to this framework, developers are able to apply creative solutions, and many of these components can be used in both React applications and mobile applications using React Native.


React works best for advanced user interfaces that don’t require SEO. In a place where the application logic is so difficult, user actions are non-standard and advanced. There are solutions based on serverless architecture and static hosting, which significantly increase the scalability of the frontend of such an application.


Next.js is a version of React that allows you to create complex and independent web applications. Used by many large companies around the world, this framework enables the development of full-fledged web applications by leveraging the latest React features and integrating powerful Rust-based JavaScript tools to speed up the compilation process.
