The React framework uses components to create a single application. Each component contains controls and logic. They are reused throughout the application. The data flow between components is unidirectional. Because the components are nested within parent components, it’s easy to debug and find the root cause of errors.

The basic structure of a React application consists of multiple components with logic and controls. These components can be reused throughout the application. Data flows from a top-level component, called an “App,” down to child components. React’s unidirectional data flow makes debugging errors easier and makes it easier to locate problem areas.
