There is an inherent "HOLY SH*T" moment that happens to all desktop developers when they transition to Web. You are used to one type of interaction when doing native that is pretty simple and straight forward. The real killer is the move to asynchronous development for everything. In Delphi (and C# desktop), most calls can be made synchronously be default, and simply. No so in the web (yes, you can do synchronous web calls...but you shouldn't). And that is ignoring the whole statically-type-and-compiled language to JavaScript issue. And then dealing with a huge array of libraries, patterns, and best practices that are completely unknown. Then comes out "why can't this be simple like what I was used to?" Actually, what you were doing wasn't simple at all, you were just used to it. You understood the complexity, so it seems simple. Web development also becomes simple once you understand it. But first you have to be willing to learn again.
