Client-side rendering refers to the process of rendering a webpage on the client's browser using JavaScript. In this approach, the server sends minimal HTML to the client, and the rest of the rendering and content fetching is done on the client-side.
Server-side rendering, on the other hand, is the process of rendering a webpage on the server and sending the pre-rendered HTML to the client. With this approach, the server generates the complete HTML, including the content and styling, and sends it to the client for display.
