What is React?
React is a powerful JavaScript library for building user interfaces, developed and maintained by Facebook. It enables developers to design reusable UI components and manage the state of their apps more efficiently. Understanding React’s key concepts is essential before diving into the installation process.
At its core, React follows a component-based architecture. Components are the building components of a React application, representing various user interface elements. These components can be nested within each other, creating a tree-like structure. React promotes the concept of reusability, enabling developers to compose complex UIs by combining smaller, self-contained components.
React’s virtual DOM (Document Object Model) stands out as one of its key advantages. The virtual DOM, acting as an in-memory representation of the real HTML DOM, empowers React to efficiently update and render only the essential components when the application’s state undergoes changes. This approach greatly enhances performance and aids in crafting responsive user interfaces.
