To support React's concept of unidirectional data flow (which might be contrasted with AngularJS's bidirectional flow), the Flux architecture was developed as an alternative to the popular modelviewcontroller architecture. Unlike other JavaScript libraries that provide a full application framework, React is focused solely on creating application views through encapsulated units called components that maintain state and generate UI elements. React provides a few built-in hooks like useState,[15] useContext, useReducer , useMemo and useEffect. The ReAct Toolbox.

React Hooks are an approach to state and lifecycle management in a React application without relying on class-based React components. It lets you compose complex UIs from small and isolated pieces of code called components. React creates an in-memory data-structure cache, computes the resulting differences, and then updates the browser's displayed DOM efficiently. The rules apply to both usage of hooks and the implementation of custom hooks,[19] which may call other hooks. React is a tool for building UI components. It shows both the code and the result. 1 : to exert a reciprocal or counteracting force or influenceoften used with on or upon 2 : to change in response to a stimulus 3 : to act in opposition to a force or influence usually used with against React is component-based.
