React.js has earned its place as one of the most popular JavaScript libraries for building user interfaces, and it's easy to see why. Developed and maintained by Facebook, React provides developers with a robust and flexible framework for creating dynamic and responsive web applications.
The real juicy part is the reference section. All hooks, components and API definitions, examples, practice problems are given in a self learning way. This documentation is fun to read.
You can't get wrong with React. The only UI library I have ever worked with. And I have no intention of switching it with another one. Two thumbs up for the React community.
