What is React

##React meaning

React is a JavaScript framework, and at the core of all React applications are components. A component is a self-contained module that can render some output. Components are composable. A component may contain one or more other components in its output.

In fact, to write a React application is to write React components corresponding to various interface elements, and then organize these components in higher-level components, which define the structure of the application

It is important that every component in a React application follows strict data management principles. Complex interactive user interfaces often involve complex data and application state. The surface area of React is limited and the purpose is to give us the tools to be able to predict how our application will look in a given situation.
