Whatever you think about javascript, I love the historic separation between content and interactivity. I dislike that so many static pages won't load without JS and that we're moving further in that direction. I hope the evolution towards "browser as OS" doesn't hurt the content vs interactivity separation. Could we ever lose the HTML centered model? That could mean we lose hackability and the ability to write extens…
If you look at the history of the web it's clear that the tendency has always been towards "shinier things". This "historic separation" was the result of technical limitations, see how popular Flash used to be for instance. HTML and CSS standards were always at least 10 years too late. If you wanted something that looked modern you've always had to use browser-specific extensions, plugins or, at best, "beta" features…
No, not any more than C#'s giant standard library blows my mind.
Keeping the web small is a strategic decision -- it may look like chaos, but it's really just that we realized that embracing 3rd-party libraries is a better architectural decision than polluting the core spec with features that will be outdated in a few years.
QT doesn't have these problems because QT doesn't have to be infinitely backwards-compatible. If QT makes a mistake, it can fix it in the next version. The web can't do that, so we have to be more careful. If anything, my biggest criticism of the web is that we move too quickly and stick too many "modern" features in. I would have been happy to drop Classes and Arrow Functions from the JS spec, and I would have been happy to drop `sticky` from the CSS spec. As an engineer, I absolutely don't want a hamburger menu as a core HTML component.
I've had people argue to me that HTML needs more 2-way data binding and element types -- they want the ability to tie a list to a JSON object or something, instead of needing to render out separate `` elements. These people are missing the point.
HTML is your user-presented state. We have a few elements that break this convention, but for the most part we want your final HTML to be static and human-readable. It's not for you, it's for your users. And 2-way data bindings would get in the way of that.
For laying things out and creating complicated lists, we have third-party libraries/frameworks -- and honestly, they work fine. If you think the web is overcomplicated or has too many frameworks right now, just wait until we start stuffing a new first-party component into it every time any design trend becomes popular.
And even if we did add all of that nonsense, people would just ignore those components anyway. No manager I've ever worked with has ever said to me, "you know, pure HTML select inputs look great and I don't mind them rendering differently in different browsers." I would be reimplementing them in JS anyway just to get the styling consistent between IE and Firefox. The good HTML components I can actually use are the low-level ones like simple input fields -- because they're small and simple enough that they can be styled and incorporated into larger custom-built solutions.
Heck, I've had managers complain to me about scroll-bar styling before. But sure, they'd totally be happy with a giant, pre-built, monolithic tree-view component that's using mid-2000s styling.
