Introduction React is a component-based library, and everything inside a React application is built using components. A component is essentially a reusable piece of UI, encapsulated with its logic, styling, and behavior. Over time, React has provided two main ways to create components: class components and functional components. For years, class components were the standard…

Introduction React offers two primary ways of defining components: functional components and class components. While functional components have become the modern standard after the introduction of Hooks in React 16.8, class components still hold significant importance. Many existing projects are built with class components, and understanding them is crucial for developers who may need to…

Introduction React, as one of the most widely used JavaScript libraries for building user interfaces, is based on the concept of components. Components are the fundamental building blocks of any React application. They allow developers to break the UI into smaller, reusable pieces that can be composed together to form complete applications. Among the two…

Introduction to JSX Rules in React JSX (JavaScript XML) is the syntax extension used in React to describe what the user interface should look like. It allows developers to write HTML-like code within JavaScript, making the code more intuitive and expressive. However, JSX is not exactly HTML. It comes with its own set of rules…

Introduction to JSX JavaScript XML, commonly referred to as JSX, is a syntax extension for JavaScript that allows developers to write HTML-like code within their JavaScript files. React, the popular JavaScript library for building user interfaces, uses JSX to define the structure and appearance of UI components. Although JSX looks very similar to HTML, it…

Introduction React is one of the most popular JavaScript libraries for building user interfaces. Developed and maintained by Facebook (now Meta) along with a strong open-source community, React has revolutionized the way developers think about building web applications. Its component-driven architecture, virtual DOM implementation, declarative style, and support for reusable code make it one of…

Introduction React.js has become one of the most sought-after technologies in modern web development. Companies around the world rely on React for building scalable, high-performing, and user-friendly applications. This increasing demand makes React a critical skill for developers who wish to pursue successful careers in front-end or full-stack development. However, simply learning React basics is…

Introduction React.js is not just a standalone JavaScript library for building user interfaces. Over the years, it has grown into a massive ecosystem supported by numerous tools, libraries, and frameworks. This ecosystem enables developers to move beyond building simple components and create complete, scalable, and production-ready applications. From state management and routing to styling and…

Introduction Learning React.js can be an exciting journey, but it can also be overwhelming for beginners if they do not start with a clear plan. React is one of the most popular JavaScript libraries used for building modern web applications, but mastering it requires structured learning. Without clear goals, learners often get distracted by countless…

Introduction Modern web applications are highly dynamic. They involve frequent updates to user interfaces, whether through real-time data, user interactions, or state changes. Managing these updates efficiently is critical for maintaining smooth performance and responsiveness. In traditional web development, direct manipulation of the Document Object Model (DOM) was common, but this approach often caused performance…
