Can we sue Oracle back for any of this?
Oracle? Oracle owns Java, not JavaScript.
Edit: mea culpa! Sun owned both!
They ended up with Javascript trademark (afaik, because the name was too close to Java) too. Sued node.js over something related.
Apparently the JS name was selected and announced in partnership with Sun from the very beginning, and Sun had the copyright over both Java and JapaScript up until the acquisition by Oracle. I had no idea, but that makes perfect sense.
Sun, afaiu, was part of a large committee on js without any particular leadership. They got the committee to agree to giving it trademark by complaining/threatening that the name was too close to java. Sun got trademark 4 years after Netscape started support for js. ECMAscript was mostly the same committee without SUN ownership/trademark.
Not the best with js, but that quiz was fun.
Alright, enough making fun of languages that suck…let’s talk about JavaScript.
Except for some reason “2” is interpreted as a month, and the year is set to 2001.
Aight I’m out
“12.1” is interpreted as the date December 1st, and as before for dates with no year the default is 2001 because of course.
it gets better and more coherent the deeper you go :P
It only took one question for me to start wanting to flip tables.
Ha this is even worse than I could have imagined!
If you’re not very familiar with JS, watch the Wat talk before taking the quiz to know what to expect from this wonderful language.
And then promptly get yourself familiar with how the language actually works. https://github.com/getify/You-Dont-Know-JS
People who complain about JS often assume it has features of other languages and fail to realize it has its own architecture and winding history.
The quirks in this quiz aren’t even universal, and vary based on which browser you’re using. See the table at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse#non-standard_date_strings
Also I got 13/28 😑
I got 10/28, but I was crying after the 7th question
I scored 13/28 on https://jsdate.wtf/ and all I got was this lousy text to share on social media.
Oof. I’ve been a JS dev since 1998.
Can we start a new web with a better language/platform already?
Google tried to do that with Dart, and failed. In fairness Dart 1 was much worse than Dart 2… So maybe that was a good thing because there’s no way they’d have been able to improve Dart as much as they have if it was part of the web.
For dates there finally is something better anyway: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal
Dart is fucking amazing and it compiles to native code, transpiles to JS (with some restrictions on concurrency because of web workers) and also supports WASM.
Really if you want to write async and stream based code Dart is very good
There’s wasm if you need to target browsers.
Yes and no. Wasm has no “standard library” so if you wanted to use Dates, your wasm would need to have its own implemation bundled for when the user visits the page. Ditto for everything else including string support! As you can imagine having to ship all this basic functionality can bloat the wasm and slow page loads.
You also can’t fully escape JS, as the only way wasm can interact with the page & browser are through the JS functions you write and make available to your wasm. I suppose you could take advantage of this to not have to ship your own standard library & use the JS Date implementation, but at that point why not just use JS?
Wasm has strengths but it’s not suitable for replacing JS for everyday websites.
Why? Why not improve JS (e.g. with Temporal), especially given how excellent Typescript is?
JS is a lost cause.
How? It’s easy not to run into the common issues by using TS. What’s so bad about it that we should throw away the existing ecosystem?
Please give arguments instead of platitudes.
You don’t need to use TS to avoid common issues. If you add an empty object to an empty array and expect a meaningful result, the problem sits in front of the keyboard.
Sure, discipline can prevent some errors. But it’s always possible to run into wrong type assumptions, and I’d say type coercion and null/undefined access make up a fairly large percentage of non-logic errors. You can entirely prevent those using Typescript, which is why it’s so useful.
Static type analysis is always a good idea if you’re writing more than a couple lines. IMO Python is the worst offender with its
kwargsetc. - discoverability and testability is just so bad if you’re following common Python idioms.
I wouldn’t call typescript excellent, if I did it would be on a very low standard.
It unquestionably is excellent. Can you name another language in common use with a type system that’s close to the expressiveness of Typescript?
I scored 10/28 on https://jsdate.wtf/ and all I got was this lousy text to share on social media.
I am a frontend dev. JavaScript (well, TypeScript) is my bread and butter. Even knowing its quirks I never would have thought how inconsistent
Dateactually is. I encourage everyone to try this quiz.This is what JavaScript haters should bring forth, not
0.1 + 0.2 !== 0.3!Or the ones where people point out how inconsistent JS is with adding strings to numbers.
Yeah, maybe don’t do arithmetic on numbers as strings?
Floating point rounding issues are basic comp science issues. Hopefully nobody thinks that those are JavaScript quirks.
Unfortunately, people do.
There is a reason almost everyone use some Date lib, like Luxon and not the built in. And well, having a horrible built in lib that they can’t change due to legacy code breaking is nothing really new or unique to JS.
The built-in lib is fine for basic stuff unless you do some crazy shit like expecting
"2"to parse as a valid date.For very basic things maybe, but it has a lot of other weird problems and restrictions. Mutability, no real timezone support, very limited arithmetic, to name a few. As soon as you move beyond the very basic, you want someting more robust.
Nobody understands JavaScript. It’s the quantum mechanics of the software world.
I got a 4/28 and got told I would have scored higher if I guessed at random. Ouch. (I am not a dev)
I mean, for what it’s worth, I’m a seasoned dev and just did a run where I tried to answer everything as it makes sense to me (which is “throws an error” or “invalid date” for all of them) and I also got a score of 4/28.
…and two of those points were given to me, because the quiz interpreted my answer differently than I meant it.
In other words, this quiz exists to highlight that JavaScript’s Date functions make no sense.
