Someone boo boo’ed the label making
document.write(('b' + 'a' + + 'a' + 'a').toLowerCase());This outputs “banana”
*old man yells at javascript*
Jesus, I thought you made a typo until I tried it. Gotta love those unary operators…
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.
well… it’s true, that is not a number.
Sorry Nan, but we really need that squash
I’m sure it’s got sodium and nitrogen in it 🤷
Goes well with naan bread.
Sodium nitride
Na3N
Little Bobby String we call him…
Free squash.
Did you try sum(squash[0, 3], na.rm = TRUE)?
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
Where I live, shopkeepers are obliged to use the posted prices if it advantages the consumer.
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.
Technically correct
That means it’s free.
Not necessary, they may just take payment in BJs
Nilfs.
You can’t fool me. Nan is flat. These aren’t flat.
Nan died of a stroke. We buried her 3 years ago.
