What is the main task of CSR technology in web development?

The main task of CSR (Client-Side Rendering) is to transfer the process of rendering web pages from the server to the client (browser). Instead of the server sending a complete HTML, it sends a minimal framework and JavaScript, which then on the client forms and displays the page content.

This allows:

• Improving interactivity and responsiveness of the interface.
• Reducing server load.
• Creating single-page applications (SPA) with dynamic content updates without reloading the page.

Example: a React application where the entire UI is built in the browser after loading the scripts.
