Thanks for this. Looks like it's going deep into "client side".

Thing about "Google.com" (I used Facebook/Gmail) is that when server side stuff is of interest (as it was for this cloud engineer job), then I also want to hear about geo DNS, reverse proxies, LBs, CDNs, eventual consistency, distributed storage, etc, all the complexity that is happening once that cat video appears in the browser.

Then again we can go back to JS, CSS, JIT and others' space
