Found at the grocery store

Very dangerous. If you buy this, NaN money will be deducted from your bank account and thus your resulting amount of money will also be NaN.

Where I live, shopkeepers are obliged to use the posted prices if it advantages the consumer.

I watched a video about these the other day some dude on YouTube seems to have hacked together a program to put whatever you want on them you can find the video here if you're interested here

document.write(('b' + 'a' + + 'a' + 'a').toLowerCase());
This outputs "banana"
- old man yells at javascript
  
  Sadly the problem is that the old men are the ones who know how to use the JavaScript and the young men are the ones who have no fucking clue what they're doing anymore.
- Could someone explains this to some of us who haven't learnt these cancer yet?
  
  Javascript has a tendency to "just work" even when it might be a better idea not to. That is achieved by making assumptions and defaulting to certain pre-defined behaviors where most other languages would just stop. Unless something truly catastrophic happens, JS always tries to find a way to keep the code running. Good or bad, that's by design just how it works.
  That is an example of this tendency. Normally the " 'a' + + 'a' " bit should be an error case, because that does not make sense. Where most programming languages would throw and error and stop execution, javascript just soldiers on. It assumes the center bit is an addition of numbers. Except since there's no number there, it automatically injects the value that represents invalid numbers, which is "nan" for "not a number". Then, since that "number" is surrounded by letters, it parses that number into a text value, which is the string "nan" itself. And then finally it adds all the letters together to form a banana.
  There are plenty of weird ways to get JS to give you stupid results back. Shit like these are not bugs with the language, it's just JS working as intended. Except the way language works as intended can lead to actual bugs very easily, is the problem.
  
  Watch this talk, it's funny and explains this well; https://www.destroyallsoftware.com/talks/wat
- Jesus, I thought you made a typo until I tried it. Gotta love those unary operators...

Technically correct
- Forget comparing apples to oranges. I'm comparing squash kabochas to numbers (they aren't)

Sodium nitride
- Na₃N

Free squash.

That means it's free.
- Careful there! NaNs are contagious like a virus. Whats 1 + NaN? NaN. If you try to buy it your credit will becomes NaN. Then when you try to pay it off your bank balance will be NaN too. It has happened to me. Now I owe NaN to the local mafia and they expect a payment this week or else they are taking my thumbs.
  
  Sounds like prions.
- Not necessarily, they may just take payment in BJs
  
  Nilfs.

Is this some fucked up form of sodium azide I'm too stupid to understand

well... it's true, that is not a number.

Goes well with naan bread.

Sorry Nan, but we really need that squash

I'm sure it's got sodium and nitrogen in it 🤷

You can't fool me. Nan is flat. These aren't flat.
- Nan died of a stroke. We buried her 3 years ago.
  
  Kabocha. Amen

Did you try sum(squash[0, 3], na.rm = TRUE)?

Little Bobby String we call him...

Not a nutmeg?

Finally, gourded Sodium Azide
- Wikipedia: Sodium Azide... used to inflate car air bags... decomposes violently.
  😎Neat.

Once upon a time, when programmers still tested their code before moving them to production,...

Is there a subtle way that one might damage these digital price tags to fuck up the store's aspirations at surge pricing? You know, so we can watch to make sure nobody does that...
- Ay LMAO
  Seriously?
