What is react principle

Question

React

Answer 1

React is a JavaScript library known for its key principles: component-based architecture, unidirectional data flow, virtual DOM, declarative syntax, efficient updates, and platform agnosticism. It promotes reusable and composable components, ensuring modularity and code reusability. Data flows in a predictable manner from parent to child components through props, preventing direct modifications. React's virtual DOM optimizes rendering by selectively updating only the necessary parts of the actual DOM. Its declarative syntax simplifies UI development by describing the desired state rather than manual DOM manipulation. Efficient updates are achieved through reconciliation, minimizing unnecessary re-rendering. React's platform agnosticism allows building applications across web, mobile, and desktop platforms. These principles contribute to React's popularity and effectiveness in creating scalable and maintainable user interfaces.
