CSR
CSR (Client-Side Rendering) is a web development approach where the browser downloads a minimal HTML page and then uses JavaScript to dynamically render content on the client side. It shifts rendering responsibilities from the server to the user's device, enabling highly interactive and responsive single-page applications (SPAs). This method relies heavily on frameworks like React, Angular, or Vue to manage UI updates without full page reloads.
Developers should use CSR for building dynamic web applications that require rich user interactions, such as dashboards, social media platforms, or real-time tools, where seamless navigation and state management are critical. It's ideal when initial load time is less important than post-load performance and interactivity, though it may impact SEO and initial page load compared to server-side rendering.
