Not calling the function would be evidence of further derangement in the design.
Such a thing has been perpetrated in C. In C, you can repeat designated initializers. like
foo f = { .a = x(), .a = y() }
The order in which the expressions are called is unspecified, just like function arguments (though the order of initialization /is/ specified; it follows initialization order).
The implementaton is allowed to realize that since .a is being initialized again by y(), the earlier initialization is discarded. And it is permitted not to emit a call to x().
That's just like permitting x() not to be called in x() * 0 because we know the answer is zero.
Only certain operators in C short-circuit. And they do so with a strict left-to-right evaluation discipline: like 0 && b will not evaluate b, but b && 0 will evaluate b.
The initializer expressions are not sequenced, yet they can be short-circuited-out in left-to-right order.
It is not. In fact, it is all the modern design sensibilities and front-end frameworks that make it nearly impossible to make accessible things.
We once had the rule HTML should be purely semantic and all styling should be in CSS. It was brilliant, even though not everything looked as fancy as today.
You only need to use scripts to move focus and provide keyboard controls if you have done something to mess with the focus and break the standard browser keyboard controls.
If you're using HTML/CSS sensibly then it's accessible from the get-go by dint of the browser being accessible.
> Also, when was that semantic HTML rule? You make it sound like ancient history, but semantic HTML has only been a thing since HTML5 (2008).
HTML5 added a million new tags, but HTML4 had plenty of semantic tags that people regularly ignored and replaced with <div>, for example <p>, <em>, <blockquote>...
”You only need to use scripts to move focus and provide keyboard controls if you have done something to mess with the focus and break the standard browser keyboard controls.”
That is straight up untrue. Some ARIA patterns require developers to implement focus management and keyboard access from scratch.
For example, ”Correct implementation of the tree role requires implementation of complex functionality that is not needed for typical site navigation that is styled to look like a tree with expandable sections.”
But sometimes you do need that kind of widget for something else.
Sorry, I completely forgot about the existing semantic tree view element that exists and can be interacted with visually but doesn't provide any accessibility or keyboard support because the browser manufacturers decided to skip that one.
Or are you talking about a situation where the developer has implemented a custom component (aka "done something") which doesn't use the native focus system and therefore requires additional work to make accessible?
If by ”done something” you mean the devs made custom widgets have the proper ARIA roles so they’re usable for people who use a keyboard to navigate, or who need screen readers and their plethora of different navigation modes. This is usually the case when a suitable standard component does not exist or is not well supported across browsers. Hierarchical tri-state checkboxes come to mind.
The native focus system typically works just fine, but JS is needed for keyboard interactions and to set things like aria-activedescendant.
For ca. ten years, the advice was to pointlessly "replace <i> with <em> and <b> with <strong>" and it utterly screwed over most new web developers' understanding of semantic tags. There are many reasons to use italics (and they vary between languages) but "emphasis" is just one of them, and none of the others ever materialized as tags.
It would have been far better to have recommended <i class="emphasis"> and <i class="media-title"> and <i class="snarky-aside"> etc. than to have added the <em> tag and said "just use it instead of <i>".
I'm not saying the ideal frontend dev writes no JS. I'm saying they write as little as possible. Some times you need JS, nothing wrong with that. The vast majority of the time you don't. And if you do I'd say it's a self-imposed requirement (or a direct/indirect result of a self imposed requirement) most of the time.
Recently I took a little dive into making some pages, that have fallback for when the user doesn't run JS. Those pages are polling an API and displaying updated status. I made sure the pages can be reloaded and show updated status information, and telling the user, that they can simply refresh the page to get that updated information, but only showing that hint about reloading, when they do not run JS. Thus I built a workflow, that people can use whether or not they run JS. I did that, because I think it is the right thing, and because I often preach, that most sites should work without JS.
For me as a mostly backend dev, this was actually quite easy to achieve. Tiny modification of the backend API, some work in the frontend using JS to remove hints that should not show when JS is running, and voila, it works. Of course my pages are very simple in nature, but the same principles can be applied to larger pages. One could even link/direct to different pages, depending on the user running JS or not, and then have a workflow without JS and one with JS. It is all possible and only a matter of wanting to make an effort. Of course, modern JS frameworks do not really encourage this kind of design. Though server side rendering becomes more popular these days, I don't think we are quite there yet.
A page that is blank when not running JS has exactly zero accessibility.
Some of those are fixes for misbehaving javascript like disabling nonessential alerts, stopping blinking, reducing animation; some are antipatterns like opening new windows, changing link text, colors, scrolling.
A11y is mostly handled by just using semantic html.
The designer, in my experience, is totally fine with just using a normal select element, they don't demand that I reinvent the drop-down with divs just to put rounded corners on the options.
Nobody cares about that stuff. These are minor details, we can change it later if someone really wants it. As long as we're not just sitting on our hands for lack of work I'm not putting effort into reinventing things the browser has already solved.
I hope in the future I can work with that kind of designer. Maybe it is just my limited experience, but in that limited experience, web designers care way too much about details and design features/ideas/concepts, that are not part of HTML or CSS and then frontend developers would have to push back and tell the web designer, that form follows function and that the medium they design for is important. Basic design principles actually, that the designers should know themselves, just like they should know the medium they are targeting (semandic HTML, CSS, capabilities of them both, a tiny bit about JS too), to keep things reasonable. But most frontend devs are happy to build fancy things with JS instead of pushing back when it matters. And not so many frontend devs want to get into CSS deeply and do everything they can to avoid JS. So needless things do get implemented all the time.
The designer wants huge amounts of screen space wasted on unnnecessary padding, massive Fisher-Price rounded corners, and fancy fading and sliding animations that get in the way and slow things down. (Moreover, the designer just happens to want to completely re-design everything a few months later.)
The customer “ooh”s and “aah”s at said fancy animations running on the salesman’s top of the line macbook pro and is lured in, only realising too late that they’ve been bitten in the ass by the enormous amount of bloat that makes it run like a potato on any computer that costs less than four thousand dollars.
And US/EU laws are written by clueless bureaucrats whose most recent experience with technology is not even an electric typewriter.
There's no scrollbar but scrollback works with alt+page_up or scrolling with the mouse wheel or touchpad. They do mention they'll implement scrollback search and scrollbars in 1.3.
Which defaults? The programming languages I’ve worked with don’t have defaults for everything related to formatting. Editor defaults don’t work, since not everybody uses the same editor. So you have to make a choice somewhere.
A lot of (relatively) recent languages do have defaults. Go and rust both come with an auto formatter out of the box, and defaults that are sane enough to just run with
Ah yeah, in those cases it is possible to just use the defaults.
Come to think of it, I have worked with Deno, which comes with a formatter (and linter and testing library) and I’m a fan. Saves a couple of dependencies, some config files and a bit of mental overhead when creating a new project.
