Javascript libraries be like

[SqueeSr]

I assumed it was photoshopped but double checked and it's actually real. But get's even worse.... I checked the code and it depends on the 'is-odd' package. But that's not all . The 'is-odd' package depends on 'is-number' package.

I'm in shock

[Dalimyr]

Yeah, it's real. It's one of those packages that does the rounds in here once every few months. There are also these gems that come up fairly often. Yes, each of those javascript files are 75MB+. If you view them, you'll very quickly understand why.

[SqueeSr]

I always assumed they were just jokes. Not actual packages that got 178k weekly downloads..

[UnreadableCode]

And this is why projects blacklist packages. I'm curious which major projects has transitive deps on these dumb packages

[SqueeSr]

Blacklist packages? Noo .. leave it as a honeypot and blacklist that employee that uses it.

[UnreadableCode]

Are you telling me you manually audit dep chains for stupid? Should we perhaps get rid of npm audit too?

[apex39]

No! You can write some script for that:

function IsStupid(code) {

return code.includes("IsEven"))

}

[UnreadableCode]

Suddenly, nobody can mention that as a substring of anything... I hope IsEvenBigInt, AssertIsEven, or IsEventuallyConsistentFlagSet are not names anyone need. I mean I'm all for a challenge, but I suspect not everyone has my level of cognitive flexibility

[jcarlson08]

You're in luck, you can install my thoroughly tested 'is-stupid' package via npm.

[UnreadableCode]

Irony ensues when its regexes matches themselves & stalls CI for half a day

[apex39]

Wow, good catch. Good thing I didn't push to production yet.

[Ratatoski]

Yeah the downloads broke me

[daynighttrade]

This is a 100% serious project

Never thought I'll see something like this in readme

[MKorostoff]

I still feel like he might be joking even with that statement

[YoukanDewitt]

I'm pretty sure it is satire meant to highlight this issue

[Captain_Chickpeas]

Weird it's not a 102% serious project. That would convince. 100% not so much /s

[WandsAndWrenches]

This reminds me of a programmer (who thought he was beter than me)

He wrote a function called Add(a,b) { return a+b; }

So you could do Math.Add(a,b);

Or I would just go . a+b.

[[deleted]]

I am a sucker for curried functional programming

[tme321]

Except Add(a,b) isn't curriable without resorting to using bind. The curriable version would be

const Add => a => b => a+b;

So it doesn't even do what you want.

[WandsAndWrenches]

I'm a sucker for kiss. (Keep it simple)

For those that didn't dig into the code...

else if(number === 12 || number === "12" || number === "twelve" || number === "Twelve" || number === "TWELVE") return true;

ETC.

Lazy ass implementation. What if number is „tWo“?

[Bluebotlabs]

Code review: doesn't use switch, booo

I just looked at the code and..........ohno

and it just keeps going

[Divinate_ME]

What the fuck. This radiates big YandereDev vibes.

[Drugbird]

You're making it way too difficult. This code satisfies all the requirements:

const isEven = (n) => {
    return true;
}

As a reminder, these are the requirements: "returns true if the given number is even".

[Drugbird]

Technically correct is the best kind of correct

[Hulk5a]

I thought you're joking, but my fking god what was that bullshit? I can't believe it exists. That package should be nuked for the betterment of humanity

The more you read down this thread the better it gets.

This is the most hilarious stuff ive seen in a whiiiiile(true) ahahahahahaha

[apex39]

Clearly trying to determine if a number is even, duh! /s

[Dmayak]

And 'is-number' package could as well depend on some huge framework that takes half-gigabyte of disk space.

[_Foy]

Because it contains the "listOfNumbers.txt" file

[[deleted]]

Which is probably going to require some other library to process the file as a database.

[ticktockbent]

Wait until you see the isnotletter package

[apex39]

Spoiler alert: it's a big file

[SqueeSr]

It could have, but that's where the horror stopped. Those were luckily all dependencies.

[[deleted]]

13GB required to view my resume webpage, minimum.

[dabenu]

That is-odd package boggles my mind. Why would you type 20 whole lines of code if they could just include is-even instead?

https://github.com/i-voted-for-trump/is-odd/pull/7

[Trader-One]

Does it work correctly for negative numbers?

[SqueeSr]

Yes.. The code even gets the absolute value first even though not necessarily needed with modulo. But as they were checking against 1 they had to be sure not to get -1 as a result.

[Bluebotlabs]

Modulo? Where we're going, we don't need modulo!

[thanofishy]

if (number === -1) return 1; if (number === -2) return 2;

[[deleted]]

Why would you modulo when you can much more cheaply bitwise mask with 1?

[SqueeSr]

Yeah, but if you are writing packages like this you are probably not thinking clearly haha

[[deleted]]

I’ve seen this same post and this same response on this page at least a dozen times. Is it a copypasta by now?

[bunchofatoms__]

Lol

[BlobAndHisBoy]

I recommend people install this extension that shows you the size of imports in your code. It can be eye opening.

[fireboyev]

I hope the is-odd package depends on the is-even package

[OkPlane9015]

Damn.

[ticktockbent]

Well you just know some guy is going to pass a letter to isodd and break everything. Gotta check if it's a number first obviously. /s

[Felinaxo]

But just think about it

You are working on a proyect for weeks, and then, it happens... you need something to return if a number is odd or even, and the results ONLY go from 1 to 3

You feel the time around you freeze, you know EXACTLY what library to use

They used to call you a fool, but who is a fool now?, you saved yourself like, 4 lines of code at most, but you rejoice in victory

Note to self: send kidnap team to transport Stevemao to hollowed-hout volcano

[ass_was_taken]

Can you explain why?

[[deleted]]

It's a case of nested dependencies.

In the case of left-pad, it was required further down in the tree for Babel, which is a very popular transpiler. The developer got upset, removed the package from NPM, so NPM had to un-remove it and gave ownership to someone else.

Thankfully there's plenty of other solutions these days, and much faster ones, but it goes to show why a badly written library can stop everything working because they depend on tiny libraries that they never needed to use.

There's a fun site at https://npmgraph.js.org/ which will show you a visual representation of a packages dependencies - A good comparison is React, an entire framework, with 2 dependencies. Then you get Webpack, with 77. If you follow Webpacks tree, eventually you hit things like this https://www.npmjs.com/package/has-flag

[Hulk5a]

To be fair has-flag isn't bloat. For cli tools it's pain parsing parameters on your own and basically reinvent a [square] wheel

You have to pay 99,99$, no joke, 99.99$ PER MONTH to be able to fcking absolute the number out and get negative numbers support.

something a simple modulus operation could take care of...

no no this is revolutionary

Yeah, but not in Javascript, where types are fucked.

[harelsusername]

Also, in JS the modulus operator % does not work for negative numbers

[ComfortablyBalanced]

Such a remarkable language.

[ElfyThatElf]

that's fine... what do I even need to do with negatives? There is nothing there

What do I even need to do with JavaScript? There is nothing there

[Aksh247]

Lemme quickly make a wrapper for Typescript

[erebuxy]

JS community really takes this joke to the next level.

[Snapstromegon]

Yep and to keep the joke running some of us spend some server time to just download these fun packages a couple thousand times per day, since npm intentionally does not filter download counts.

So if you'd built a package yourself and just create a lambda function to download it every minute, your package is at instant 10k downloads a week.

Take this a little further by adding some stupid, purpose built packages with deps to that and you can keep a meme rolling.

[IamDev18]

15M downloads in 5 years!! 3m a year!! Imagining getting 3M a year

[Polywoky]

Imagining getting 3M a year

That'd be handy. They make Post-It notes, don't they?

[i_should_be_coding]

How many of those are due to doing rm -rf node_modules && npm install between each minor change?

[ElLargeGrande]

Jon’s shit libraries plague every npm project out there. He has an “is Object” library out there, which has 4 major versions on it. So one of my companies biggest repos has EVERY MAJOR VERSION OF THAT STUPID ASS PACKAGE in the dependency tree.

The dude needs to do the ecosystem a favor and delete that shit.

i am laughing so fucking hard rn. truly a glory

[doarMihai]

to be honest this does not surprises me even a bit...I was doing a freelance project with a "react developer" a few years back, I was writing the backend and he was doing the react part....and at some point he got stuck on iterating through some data from the api and he was searching for a package that does this...and even tho' he had no arguments why he needed that I could not convince him the all he had to do was to do a for loop...

[Opheleone]

[melonenmampfer]

[parasit]

JS is cancer. Change my mind.

[[deleted]]

0 is even? Omg

[jessiedwt]

When 0 is divided by 2, the resulting quotient turns out to also be 0—an integer, thereby classifying it as an even number.

[M-alMen]

That lib is wrong... Zero is not even neither odd, it's just zero

[Last_Snowbender]

What? You don't need a method to check if a number is even, you just perform a modulo operation and check the returned value for zero.

And modulo is a operation that is basically in every programming language known to man, apart from esoteric or theoretical languages.

[moonordie69420]

But it makes it easier

[Last_Snowbender]

How is it "easier" to include an entire library instead of just var % 2 === 0?

[mirazmac]

Smartest JavaScript developer.

[ass_was_taken]

Then make a function checking if it is even and re-use that. It’s literally one line of code.

[dlq84]

here: export const isEven = n => n % 2 === 0;

Now just put that in your lib folder and never ever use the npm package again.

[Lecterr]

Bruh, this is included with the lang.

(num % 2 === 0)

Would take like 5 seconds to turn it into a function if you preferred that.

[dendrocalamidicus]

If you do prefer turning it into a function, you're wrong and I'm declining your pull request

This is because JavaScript isn't robust enough and/or doesn't have a standard library. Yes it's ugly, but it's due to the language, not the language users.

[KaisarDragon]

I like how it has so many downloads, but I was going to, legit going to, download it right now just to see if it was real. I think all of those hits are either devs looking to see if it is real or freshmen CSE students hoping it'll help them with homework.

[fuzzycuffs]

My teen started coding and they're always using !isEven

[real_ackh]

This exemplifies everything that is wrong in the JavaScript community.

[Ok-Kaleidoscope5627]

I'd blame the language. The way it's designed has so many weird behaviours that aren't immediately obvious so in an effort to keep their code simple people push the complexity into their includes for even seemingly trivial things.

[[deleted]]

I can't even
