The process of turning your code into visible elements on the screen.
Rendering is the process where code becomes pixels on your screen. Your code describes what to display (HTML, CSS, JavaScript). The browser reads that description and paints it to the screen.
In React, rendering means executing your Component function to create a virtual representation, comparing it to the previous render, and updating only what changed. When state changes, React re-renders just the affected parts. useEffect runs side effects after renders. CSS states trigger visual re-renders.
Next.js provides server-side rendering for SEO and performance. Loaders fetch data before rendering. Actions trigger re-renders after mutations. Protected routes conditionally render based on Authentication. Understanding rendering helps you optimize performance and build fast, responsive applications.
