REACT: A free and open-source JavaScript library

React, also known as ReactJS, is a free and open-source JavaScript library developed by Meta (formerly Facebook) in 2013. Primarily used for constructing user interfaces (UIs), React has gained widespread popularity for its efficiency and flexibility. Its key strength lies in the creation of dynamic and reusable UI components.

[Here library means cluster of pre-written code snippets that developers can import and use across different parts of a program. In React's case, it provides a set of tools and components, enabling code reusability and simplifying the UI development process.]

Component-Based: React follows a component-based architecture, enabling developers to create reusable UI components.

Declarative Syntax(JSX): React uses a declarative syntax, enhancing readability. Developers describe the UI, and React handles updates.

Virtual DOM: React optimizes updates with a Virtual DOM, improving performance by updating a virtual representation first.

Single-Page Applications (SPA): React excels in SPAs, delivering seamless and fast user experiences without full page reloads.

Library vs. Framework: Libraries offer flexible functions, giving developers control over the application flow. Frameworks, on the other hand, dictate overall flow, calling your code as needed.

In summary, React empowers developers to build modular, efficient, and interactive user interfaces, making it a valuable tool for creating modern web applications.
