Dude, his point is that if you did not implement partial rendering on a big file, the browser will have to work extra hard to render that shit. Not to mention if you add any interactivity on the client side like variable highlighting that needs to be context aware for each language… that basically turns your browser into VSCode, at that point just launch the browser based vscode using the . shortcut.

It’s not a matter of the server side of things but rather on the client side of things.
