The Browser Hacker's Guide To Instant Loading

The web has lacked a predictable story for loading content efficiently in a way that gets you interactive in just a few seconds. Developers have a number of primitives to get there: preload, preconnect, prefetch, HTTP/2 server push, module loading, service workers. . .the list goes on. Yet the interaction between these different pieces of the web is still not well understood or explained.
