React :-

• Component-Based Architecture :

React follows a component-based architecture, where UIs are broken down into reusable and self-contained components. Each component can have its own state and properties, and they can be composed together to build complex UI hierarchies.

• Virtual DOM :

React uses a virtual DOM (Document Object Model) to efficiently update and render components. The virtual DOM is a lightweight copy of the actual DOM, and React uses it to determine the minimal number of updates needed to keep the UI in sync with the underlying data. This approach helps improve performance by minimizing actual DOM manipulations.

• JSX Syntax :

React uses JSX (JavaScript XML) syntax, which allows developers to write HTML-like code within JavaScript. JSX makes it easier to define component structures and their rendering logic. JSX is transpiled to regular JavaScript by tools like Babel, enabling React code to be compatible with all browsers.

• Unidirectional Data Flow :

React follows a unidirectional data flow pattern, also known as one-way binding. Data flows from parent components to child components through properties (props). Child components can trigger callbacks to communicate with their parent components. This approach helps maintain a predictable and understandable data flow in React applications.
