React.js makes it painless to create and build encapsulated components that manage their own state, then compose them to make complex, interactive UIs.
Why use React.js?
The way React.js incentivises you to build applications makes them highly maintainable.
Due to its component-based approach, all its elements are reusable and adaptable.
React.js is fast. Whether it’s for UI rendering or server-side rendering, it supports both with ease.
