  Conditional Rendering in React Conditional Rendering is one of the most useful concepts in React. It means showing different content on the screen depending on a condition. For example: If a user is logged in → show Logout If a user is not logged in → show Login If a student has passed → show Congratulations If a product is available → show Buy Now If data is loading → show Loading... React does not have a separate if rendering tag. Instead, we use normal JavaScript conditions such as if, the ternary operator, &&, and switch to decide what should appear in the UI.

What is React? React is a popular JavaScript library used to build user interfaces (UI) for websites and web applications. It helps developers create interactive, fast, and modern applications by breaking the user interface into small, reusable pieces called components. Think about a shopping website. It contains a navigation bar, product cards, a shopping cart, a search box, and a footer. Instead of writing all of these sections as one large block of code, React allows you to build each part as a separate component. These components can then be reused wherever they are needed. React focuses only on the user interface, which is the part of the application that users see and interact with. It works well with other libraries and tools for handling tasks such as routing, state management, and connecting to databases. Today, React is one of the most widely used technologies for front-end web development because it makes building complex applications easier to manage and maintain.
