Component-Based Architecture:React follows a component-based architecture, where the user interface is broken down into small, reusable components. Each component represents a part of the UI, and these components can be combined to build complex user interfaces. This approach makes it easier to manage and maintain large codebases.
Virtual DOM:React utilizes a Virtual DOM to optimize rendering performance. Instead of updating the actual DOM directly, React creates a lightweight copy of the DOM (Virtual DOM) and performs all updates on it. Then, it calculates the difference (diffing) between the previous and current Virtual DOM states and efficiently updates only the necessary parts of the actual DOM. This process minimizes expensive direct DOM manipulation and improves rendering speed.
Declarative Syntax:React follows a declarative programming paradigm, which means developers describe how the UI should look based on the application’s state. They don’t need to worry about how to achieve the UI updates; React takes care of the underlying processes.
One-Way Data Binding:React enforces one-way data binding, which means the data flows in a single direction, from parent components to child components. This unidirectional flow of data simplifies application logic and makes it easier to debug and understand how data changes propagate.
Component Lifecycle Methods:React provides several lifecycle methods that allow developers to perform actions at specific stages in a component’s life, such as when it’s created, updated, or destroyed. These lifecycle methods enable developers to control component behavior and handle events efficiently. Rich Ecosystem: React has a vast ecosystem with numerous third-party libraries and tools, including state management libraries like Redux and MobX, testing libraries like Jest and Enzyme, and UI component libraries like Material-UI and Ant Design.
