React.js up close

How a solution designed for Facebook became one of the most popular in the world.

React was created in 2011 on the initiative of a Facebook employee - Jordan Walke. The developer's goal was to create a JS library that would simplify the interface creation process as much as possible and provide the application users with the best experience.

The innovative front-end solution that Walke designed was originally intended only for Facebook. In 2013, however, React was made available to the community in an open-source model, and since then, it has gained immense popularity around the world. It is appreciated by developing startups and the most recognizable and significant brands, incl. Instagram, Netflix, or Uber.

What makes React.js so popular - and still gaining more attention? Technology has numerous advantages that allow businesses to accelerate. It is stable, secure, and scalable. It allows you to create perfect - both simple and complex - interfaces and reusable UI components. Furthermore, it provides the best experience for users of web and mobile applications.

Virtual DOM - React creates and stores a virtual copy of the HTML tree, so it doesn't have to load it every time changes are made to the application. This promotes efficiency - even in the most complex projects - and also enables real-time reloading of the interface.
