Speed up loading and rendering time

[jav-ed]

Let me first make it clear, I really like quarto and the features it provides. Having said that, have you ever thought of using something like https://astro.build/ or https://www.solidjs.com/. With Astro you could improve the loading time of webpages, i.e., if you have some JavaScript code that shall be only loaded if a HTML element needs it. Basically: loading only the js code that shall be executed, speeds up the loading time of a webpage.

Solidjs is something that speeds up the rendering of a webpage. So, we have some components in our HTML. Now we want to change only some of them. Instead of rerendering the whole HTML file, only update the parts which are meant to be updated.

I am looking forward to hearing about your thoughts about that topic. Also, especially why this might is difficult to achieve. The main reason, why fast loading and rendering is desired is that, generally people leave the page if it takes more than ~3 seconds to load.
