Sure, but you can get frameworks that generate that for you. I’ve written whole webpages in WASM without writing any JS.
You don’t get around reading JS documentation, though. Especially the DOM API is just documented as JS, and you basically hope that your framework makes it obvious enough how to write that in your non-JS language of choice.
This is exactly the reason why I can’t believe that was ever a requirement. I would have crazy respect for webassembly if it could stand on it’s own as it would allow people to completely move away from JS, but if JS is still in the stack in any way it will introduce a (even if it is minimal) compatibility and maintenance cost in the long run.
I used to think so, too, but on the one hand, the DOM API is absolutely massive. Going through the standardization, implementation and documentation process another time would take decades.
And on the other hand, a language-agnostic API in WebAssembly would mean specifying it WebAssembly itself. And well, it’s Assembly-like, so what’s currently a single line for calling a JS function would turn into tens of lines of low-level code.
Ultimately, you’d want code from some other high-level language to give you a summary of how you may need to call your language-specific wrapper. In practice, that’s likely even worse than translating it from JS, because the high-level call isn’t standardized.
i believe they plan to remove that requirement? at least i know they are trying to use a native wasm<->dom api instead of wasm<->js<->dom, which is slow
Big if true, do you have a link to follow that development? I’ve been curious about some languages that compile to JS+WASM but I’ve been waiting for something like this to finally cut out the middle man and give me an excuse to learn WASM directly.
There’s actually in theory all the pieces in place to use a different scripting language, because in the early days, there really were multiple. But yeah, the massive DOM API is only really standardized+implemented+documented for JS, so you don’t get around it in the end.
As the others said, though, WebAssembly is starting to become a thing and the JS boilerplate for calling the DOM API can be generated for you.
Most of the weirdness comes from being designed for the web, and specifically for working with forms. The value of a form field will always be a string, which is a simple and straightforward idea, but then the trouble showed up when we tried to make it more convenient to work that way.
Actually, most of the weirdness comes from having been originally designed in a matter of 10 days by a single engineer working to accommodate a tight release schedule.
I mean, do you think that has more explanatory power though? The type coercion rules are actually more elaborate with == than necessary for equality checking, because it was intended as a clever convenience for working with strings. If it was really all about the short timeline, wouldn’t you just skip that and do a more straightforward equality comparison, like the algorithm that === implements?
Besides, it’s not like everything in the language was conceived and implemented in those 10 days. The language has been evolving steadily since then. I’m not even sure if the modern == comparison algorithm worked that way in the first iteration.
Personally, I find it more useful to understand the context that lets me say “that’s a quirky consequence of a sensible principle,” rather than blaming it on the “ten days” legend generically.
I think the “ten days” explanation has the merit of being charitable, because it implies that Brendan Eich wouldn’t have made such short-sighted design choices under more favorable circumstances.
(I do not believe that it’s a “sensible principle” to treat text as such a fundamental form of data that a basic language feature like the equality operator should be entirely shaped around it. Surely the consequences of building an entire language around text manipulation should be apparent by considering how awkward Posix-style shells are for any nontrivial scripts.)
Well… The circumstances were that he was asked to whip up a little scripting language, that felt a little like Java and a little like Scheme, which could be used to add simple manipulations and interactions to web pages. Specifically to web pages. Not webservers, mobile apps, databases, banking systems, physics simulations, robotics… Only web pages. And nobody had even conceived yet of something like Google Sheets-- It was simple HTML forms and DOM manipulation.
IMO in that context, it makes alot of sense. I think it was probably still the wrong decision-- definitely with the benefit of hindsight, and quite possibly even at the time, even in that narrow context. Way more trouble than it’s worth.
But it’s beneficial to know that there was a principled (if misguided) reason behind it, that ties into the nature and history of the language-- It’s not simply “dude was in a hurry and not thinking.” Both are kinda true, but the former perspective helps us understand something useful, whereas the latter doesn’t get us anywhere interesting.
Can you write a website in other languages, like c# or python?
Yeah, anything that outputs HTML and CSS can do so. There’s a module for Apache to write webpages in Python (libapache-mod-python) and I’m p sure someone somewhere made a module to do it in Rust already except they’re infighting over whether tag parsing in it should be marked unsafe.
For that matter you do can write web pages in your shell eg.: bash, that’s what CGI is all about.
I guess why it’s weird because of the loose rules it follows, like what is mentioned about === and ==. There is WebAssembly which kinda acts like Javabyte code or CIL there used to be huge hype that it’s going to replace JavaScript, though it’s not used that much today. I think why there is low adoption is mainly because JavaScript is good enough, it’s widespread and easy to learn.
If you’re provided a tool that solves a problem, I don’t really get ignoring that and continuing to focus on that solved problem as if it weren’t solved because you think all the tools should solve it on principle
That’s a little bit like saying, “I don’t understand why people continue to complain about the landmine sitting right there on the ground. We’ve painted it red so you can easily walk around it, so how has the problem not been solved?”
Land mines are painted red in my shop. You want to change the language to remove a land mine that everyone competent already knows enough to step around. The problem has already been solved, so why are you continuing to complain about it?
Just to be clear, I’m not actually calling for JavaScript to change, I’m just pointing out that people are right to point out this as being a problem. Having said that, if everyone competent uses linters now so that this feature isn’t used in practice anymore, then getting rid of it shouldn’t even break anything, and arguably code which would break is already broken because it uses an operator that no one should be using, so you shouldn’t be using this code anyway.
I can sort of get down with what you’re saying, but on the other hand, we all have design constraints, inside and outside of programming, I think this is a very minor one
Using linters in a professional setting is more like moving all your actual employees into a different office and letting them use robot avatars in the original office who can never step on that landmine.
The benefit of this is that millions of other robots continue to depend on the original office being exactly as it is and many of them will never change or update, nor is their any need for them to.
Breaking backwards compatibility on the web needs much better reasoning than ‘I don’t want to use a linter’.
Not only is this really gross, it’s also straight up wrong. It’s missing a from clause, and it makes no sense for a where clause to be nested under the select. The select list selects columns from rows that have already been filtered by the where clause. Same for the limit.
Also just gonna go ahead and assume the JSX parser will happily allow SQL injection attacks…
