What is the difference between SSR, ISR, SSS 👀

SSR (Server-Side Rendering), ISR (Incremental Server-Side Rendering), and server-side streaming are all techniques for rendering and serving content to a client in a web application. Here is a brief overview of the differences between these three approaches:

SSR (Server-Side Rendering):

SSR involves rendering the content of a web page on the server and sending the fully rendered HTML to the client.
This can improve the performance and SEO of a web application, as the client does not have to wait for the JavaScript to execute before the page is displayed.
However, SSR requires more resources on the server, as the server has to do the rendering work.

ISR (Incremental Server-Side Rendering):

ISR is a variant of SSR in which the server sends the initial HTML content to the client, and then the client renders the rest of the content using JavaScript.
This can improve the performance and SEO of a web application, as the initial content is displayed faster and the server does not have to do as much rendering work.
However, ISR requires the client to have JavaScript enabled, as the client is responsible for rendering the rest of the content.

Server-Side Streaming:

Server-side streaming involves sending a stream of data from the server to the client in real-time, without waiting for the entire response to be generated.
This can be used to implement real-time features such as live updates or chat applications.
Server-side streaming requires the use of a special HTTP header, Transfer-Encoding: chunked, which tells the client to expect a stream of data rather than a single response.
