You’ll find an npm package to help you count up to 2.
(I recently learned - maybe here - that the is-even package has over 170k weekly downloads)
What’s even wilder is if you look at the code of that package, all it does is include the is-odd package and then return !is-odd. And the is-odd package isn’t much better, it does some basic checks on the input and then returns n % 2 === 1.
I thought I was missing something. JS is one of my main languages and I always just write the is-odd function myself since it’s like 10 characters. It boggles the mind that is-even has 176k weekly downloads
To be fair having a name can make things easier to read. I get that
i % 2 == 0is a common pattern and most programmers will quickly recognize what is happening. ButisEven(i)is just that much easier to grok and leaves that brainpower to work on something else.But I would never import a package for it. I would just create a local helper for something this trivial.
Exactly what I would do if I had to reuse it, especially now since I know that adding a package would actually add 2. It all just seems so…inefficient
Even if the code isn’t reused adding names to sub-expressions can be very valuable. Often times I introduce new functions or variables even if they are only used once so that I can give them a descriptive name which helps the reader more quickly understand what is happening.
Yeah, I do that with pretty much every separate operation in c# since our solutions are pretty big. Most of my JS scripts are just done in ServiceNow which are separated and named appropriately.
Also there are 40-something packages depending on it, so I guess it gets pulled automatically when they are used.
If youre lazy/busy enough, doing basic checks on the input is enough boilerplate to package out.
I’ve always looked at stuff like that as much more along the lines of performance art than anything else.
Is-even continues to be the best joke in the industry
Oh boy, this actually made me laugh out loud
This must be a “hold my beer” kind of joke and someone wanting to see how far they can take it.
- it’s easy to make fun of
- it makes every other programming language look better in comparison
- It runs in browsers
- If you hate your co-workers, then they will also feel your pain.
- You can call it “Java” to enrage other programmers
- You can compare numbers against strings without wasting time converting them
Array(16).join(“wat” - 1) + " Batman!";
JavaScript: :wide eyed and smiling: Sure why not! You’re the boss!
Python: Sighing and downing half a bottle of Advil: Sure. Why not, you’re the boss.

The scripting language formerly known as Java.
- It’s not PHP.
- I don’t know. I didn’t think I’d get this far.
- It’s not PHP
- It’s already implemented in browsers
PHP has gotten really good over the past few versions, actually. Lots of really great stuff has been added, it feels like it resembles rust more every release lol
PHP10: We now allow interop with Rust!
PHP11: We now allow writing code directly in a .php file and compile it with rustc.
Can’t forget the intermediate step of PHP 9: PHP borrow checker
It’s not Malboge.
- It runs in the browser
- Web developers know it already so we might as well
- It has the simplest multi-threaded implementation: no threads!
- You can goof off while your build system takes 20 minutes to rebuild a non-compiled language
node_modules size of a Linux distro
- Job security
- its not COBOL

It’s* not
If you are understood buy you’re audience, you have spoken correctly. Correcting someone’s grammer is pointless
I dunno what correcting someone’s grammar has to do with paying off your readers. Sounds expensive.
This isn’t speaking, but writing (or typing). Using ‘correct’ spelling & grammar helps ESL speakers read the language as well as those relying on text translation software. Some folks make typos & it’s fine to make mistakes but it’s also strange to act like it’s just as easy to understand. Apostrophes have a specific meaning & many folks rely on them for understanding.
I’m learning a foreign language now & I can tell you it is a massive stumbling block when you run into what you think is a new word, but is ‘just’ a misspelling.
My issue with this account is not its corrections, but if you want to be the correction bot, at least get the typography right too.
'is as ASCII holdover & it should be’.
I am forced to try to get a JS certification.
I am reaching the end of my rope, and starting to think of maybe putting my neck into one.
Isaac Newton said that we see far because we stand on the shoulders of giants.
Javascript is like standing on the shoulders of dwarves with brittle bone disease.

1 - Easiest way to run a script in your browser
2 - Always finds its way if inputs are bad
Nan - undefinedNaN is of type number. because fuck me.
IEEE-754
To be fair, this is actually reasonable. But it does look stupid on the face of it.
Easiest? More like… The only way.
- Ubiquitous; insane amount of libraries and probably some of the best documentation of any language
- JS lambda function syntax is nice
It leads to typescript
You get surprises from npm
I spent way too long today figuring out why my app was doing something that it’s NOT supposed to do on weekends.
I read Luxon’s docs (pretty cool lib tbh) again and again, and tried everything I could think of to get isWeekend to return a sane result.
Turns out I was pulling a somewhat older version of Luxon, where isWeekend didn’t exist. In any sane language, I expect I’d get a huge warning about a property that doesn’t exist, but alas…
Typescript helps me keep my sanity, but juuuuust barely.
If isWeekend doesn’t exist, then the weekend doesn’t exist, so it’s naturally false.
That’s why JavaScript gets pushed so hard - it’s part of the capitalist agenda to keep us working 7 days a week
That’s fair. Typescript has to cook with the existing js ecosystem.
Weren’t you getting runtime errors for the function not being found?
No, they were probably getting false every time
I don’t know how luxon works, but isWeekend could be a property instead of a function
It is. It also happens to be undefined, and checking that for truth is how I was bitten.

- Is available to be used in website scripting.
- Not quite as full of footguns as PHP (although it is close).
PHP is actually quite footgun free these days.
awaitandasyncThe part that always gets me is when people choose Js for the backend. Like I get that it’s the default thing that works on the frontend, so there’s some rationale why you might not want to transpile to it from another language. On the backend though, there are so many far better option, why would you willingly go with Js, especially given that you’re now forced to do all your IO async.
I moved from primarily ASP.Net Core backends, which is a hell of a great backend framework btw, to NestJS. Not my choice. I do what the people who sign my paychecks ask for.
I cannot begin to fathom why anyone would willingly choose JavaScript for backend. TypeScript helps a lot but there are still so many drawbacks and poor design decisions that make the developer experience incredibly frustrating. Features that are standard in ASP.Net Core, Django, or other common backend frameworks just don’t exist.
Also, don’t get me started on GraphQL. Sure, it has performance advantages for websites of a certain size and scale. But 99% of the websites out there don’t have the challenges that Facebook has. The added complexity and development cost over REST is just not worth it.
Yeah, gql in particular is a problem looking for a solution in most cases. It makes sense for facebook because they have people building frontend apps for their marketplace, and those apps need all kinds of weird combinations of data. However, this isn’t the situation for most apps where you have a fairly well defined set of calls you’re doing.
Server side rendering looks like it could be useful. I imagine SSR could be used for graceful degradation, so what would normally be a single page application could work without Javascript. Though, I’ve never tried SSR, and nobody seems to care about graceful degradation anymore.
Most pages tend be just documents and fairly simple forms. Making SPAs and then having to worry about SSR is just making a Rube Goldberg machine in most cases. I think something like HTMX is a much better approach in most cases. You keep all your business logic server side, send regular HTML to the client, and you just have a little bit of Js on the frontend that knows how to patch in chunks of HTML in the DOM as needed. Unless you have a highly interactive frontend, this is a much better approach than making a frontend with something like React and adding all the complexity that goes with it.
No one cares about graceful degradation anymore. But you can sell management on SEO. Page performance is a key aspect of search engine rankings and server-side rendered pages will almost always have a much faster initial load than client-side rendered.
You really should be doing your IO async. Do you specifically mean callback hell?
No I meant having to do async as opposed to having threads like you would in Java for example. In vast majority of cases a thread pool will work just fine, and it makes your code far simpler. Typically, Java web servers will have a single thread that receives the request and then dispatches it to the pool of workers. The JVM is then responsible for doing the scheduling between the threads and ensuring each one gets to do work. You can do async too, but I’ve found threads scale to huge loads in practice.
Green threads are functionally the same, especially in languages that can preempt.
Sure, but the scheduler figures out the scheduling automatically so you don’t have to worry about stuff like blocking.

is there a non sexist/queerphobic meaning for that term? i would assume the bigotry is the whole point.
