React.js is a JavaScript library for building user interfaces. It was developed by Facebook and is often used for building single-page and mobile applications.
React is based on components, which are reusable pieces of code that represent a part of a user interface. Each component is a self-contained unit that specifies its rendering logic and manages its state. This makes it easy to build complex UI by composing small, independent components together.
React uses a virtual DOM (a lightweight in-memory representation of the actual DOM) to improve performance by minimizing the number of DOM manipulations required to update the UI. When a component’s state changes, React will update the virtual DOM and then use a diffing algorithm to determine the minimal set of DOM operations needed to update the actual DOM.

Higher-Order Components are not part of the React API. They are the pattern that emerges from React’s compositional nature. The component transforms props into UI, and a higher-order component converts a component into another component. The examples of HOCs are Redux’s connect and Relay’s createContainer. Higher-Order Components A higher-order component is a function that takes a component and returns … Read more
