superfluous, or egregious examples of bad web dev?? Do you know what Web 2.0 is? Do you know what are React, Angular, and the other JS Frameworks?

When you create a modern webapp, a lot of data are retrieved from servers as Json and formated in the browser in Javascript. Even sometimes Css is generated on browser-side. Even more, on webapp where user login is taken into account, the display is modified accordingly.

That's the web of 2019. The approach consisting of geting remote files and launching them in a browser is really naive.

Speaking of SingleFile, it as a cli version and can handle full web 2.0 webapp without any problem. And of course, the Web 1.0 webapps work as well.

With the exception of actual XHR requests (which should ideally be for dynamic resources, and as such somewhat outside the remit of saving a webpage), I was referring specifically to JS loading JS, etc. solutions. React, Angular do not recommend/advise you to do this. This isn't a requirement in Web 2.0 or Web 5.0 or anything else.

In terms of React at least, fetch requests are not a part of the framework in any way and any present would typically be done in custom code in lifecycle methods. Even Redux, is—by default—client-side only. Stores are in-memory, actions populating them would make fetch requests with React/Redux-independent logic.

Other JS frameworks are, typically, the same. And all of that is just considering dynamic XHR. Loading scripts is much less typical, and never required. The most common application of this I've seen is the GA snippet, which mainly does it to ensure the load is async without relying on developer implementation: it's 100% unnecessary to do it this way.

So yes, unless you're distributing a tracking snippet that you expect non-devs to be blindly pasting into their wordpress panels and still have it work efficiently, generally speaking use of this method is never necessary, and commonly a red flag for poor architecture.

Sometimes we spent too much time in our own ecosystem. In 2019 most sites globally still use php and jquery.

Web 2.0 refers to the use of ajax. This refers to the early 2000s sajax, jquery..

If you want to separate angular, react, vue maybe it's web 3.0.. but wasn't web 3.0 referred to as mobile?

I think that's exactly what that person means by superfluous and egregious examples of bad web development; SPAs, javascript frameworks of that nature. :p

Yes, the debate between building a SPA with rich features or Web old pages with good SEO is eternal :) We see more and more an hybrid approach that can be called web 1.5 :)
