NaN minutes later, a truck arrives in the alley, its license plate reads "undefined". Someone gets out of the vehicle
"I have something for you"
He gives you a package. You open it. It's an [object Object]

[-] dohpaz42@lemmy.world 63 points 3 days ago

Must be from the NPM delivery service. The recipient is lucky the driver didn’t give them thousands of dependencies too.

"I got a package from Jason"

"I also got a lock"

[-] elvith@feddit.org 19 points 3 days ago

Guess why he came with a truck and not on a cargo bike...

Ah sweet, my left-pad is coming today!

[-] HenryDorsett@lemmy.world 1 points 2 days ago

You don't get dependencies in real life like that.

You work 10 years in an industry and try to get a promotion? That may be a dependency issue.

"I've been looking for you! Got something I'm supposed to deliver. Your hands only."

Wait until Null opens the door

segmentation fault

Knock knock

[-] badcommandorfilename@lemmy.world 70 points 4 days ago

You wouldn't want your code throw an exception

[-] JackbyDev@programming.dev 3 points 2 days ago

[object Object]

[-] Scoopta@programming.dev 41 points 4 days ago

As someone who mostly avoids JavaScript, I don't see the IT in this image, I just see a bad language I avoid!

[-] blackn1ght@feddit.uk 18 points 3 days ago

This isn't the languages fault, it's the developers.

[-] sukhmel@programming.dev 6 points 3 days ago

Albeit true, I want to note that some languages encourage such practices way more than others do. Also, when you've got a hammer everything looks like a ~~string~~ nail.

[-] blackn1ght@feddit.uk 1 points 2 days ago

In my mind a simple unit test should have caught this. Mock out the call to the service that sends the message and verify that it's been called with the correct message, and cover the possible failure scenarios. That said I hate loosely typed languages lol.

[-] copd@lemmy.world 5 points 3 days ago

besides NaN actually being a number, this could completely and easily be avoided with typescript.

[-] rooroo@feddit.org 5 points 3 days ago

Naaah. Good programmers know how to use as any as any to make this work in typescript as well.

[-] CanadaPlus@lemmy.sdf.org 2 points 2 days ago
[-] Scoopta@programming.dev 2 points 3 days ago

I'm assuming by this you mean the developers of JS /s

[-] JackbyDev@programming.dev 4 points 2 days ago

I promise you, people make mistakes in every language lol.

[-] davidagain@lemmy.world 3 points 3 days ago

I had the exact same reaction.

[-] HugeNerd@lemmy.ca 5 points 2 days ago

I freaking love naan! Bring it!

[-] funkless_eck@sh.itjust.works 3 points 2 days ago

NaN naan Jeremy that's insane

[-] jwt@programming.dev 30 points 4 days ago

I [object Object]

[-] altkey@lemmy.dbzer0.com 15 points 3 days ago

Is it a threat?

[-] anguo@piefed.ca 17 points 3 days ago

I kid you not, opening this post on piefed.ca gave me "Internal Server Error" the first time.

[-] mumblerfish@lemmy.world 18 points 3 days ago

I got one of those too. I called the customer service to get another path home because of disturbances, and they just have robot answering. The robot started halfway through the call just reading pure json at me, and then said "to get this information as a message press 1" or something. This is what I got:

Here is your journey from undefined to undefined: BUSS 506 towards Karolinska sjukhuset 09:36 from undefined 10:18 arrived at undefined. Link to your journey.

[-] JackbyDev@programming.dev 1 points 2 days ago

If you want those on separate lines you need to add two spaces on the end of each line!

[-] glorkon@lemmy.world 14 points 3 days ago* (last edited 3 days ago)

I'm an old fuck and I started to code in the late 80s. Fast forward 30 years, I once had to work at a WeWork. One day, directly outside of my small office space, I swear to god, a fucking hipster kid with a Macbook under his arm practiced skateboard moves. That was the exact moment I started hating working in IT. It's also what I think every Javascript coder looks and acts like.

[-] Guttural@jlai.lu 5 points 3 days ago

Youngsters these days, uh?

Now grandpa, time to take your medicine

[-] Dumbkid@lemmy.dbzer0.com 5 points 3 days ago

What's wrong with skateboards

[-] JackbyDev@programming.dev 3 points 2 days ago

I really don't care people using skate boards, even doing it around a workplace isn't necessarily taboo in my mind, but they were in the office right outside someone's door. Do it in the parking lot or something.

[-] glorkon@lemmy.world 13 points 3 days ago

Nothing. But that kid used it inside a coworking space.

[-] Matty_r@programming.dev 7 points 3 days ago

I actually wish skateboards made a come back. Much more preferable over the escooters I see around a lot.

[-] axEl7fB5@lemmy.cafe 1 points 2 days ago

What about kick scooters?

[-] marcos@lemmy.world 13 points 3 days ago

The Javascript literal interpretation of NaN never fails to amuse me.

[-] squaresinger@lemmy.world 4 points 3 days ago
"a"+"b" -> "ab"
"a"-"b" -> NaN
[-] marcos@lemmy.world 2 points 3 days ago

Yeah:

parseInt("a") -> NoT a NuMbEr
[-] squaresinger@lemmy.world 2 points 3 days ago

Sure, but the main issue here is that JS doesn't only auto cast to more generic but in both directions.

Maybe a better example is this:

"a" + 1 -> "a1"
"a" - 1 -> NaN

With + it casts to the more generic string type and then executes the overloaded + as a string concatenation.

But with - it doesn't throw an exception (e.g. something like "Method not implemented"), but instead casts to the more specific number type, and "a" becomes a NaN, and NaN - 1 becomes NaN as well.

There's no situation where "a" - "b" makes any sense or could be regarded as intentional, so it should just throw an error. String minus number also only makes sense in very specific cases (specifically, the string being a number), so also here I'd expect an error.

If the programmer really wants to subtract one number from another and one or both of them are of type string, then the programmer should convert to number manually, e.g. using parseInt("1") - parseInt("2").

[-] Viking_Hippie@lemmy.dbzer0.com 10 points 3 days ago

I'm no acupuncturist, but I'm pretty sure that it's SUPPOSED to say "naan minutes", which is time spent enjoying delicious Indian flatbread.

I guess you just eat your naan and then your ride arrives to ask you if you have any leftovers? 🤷

[-] airbussy@lemmy.one 9 points 4 days ago

At that point just throw an exception man
