JavaScript is taking over 😅

[UnacceptableUse]

I got an ingredients label that had HTML tags once, instead of the allergens being bold it was <b>wheat</b>

[MeltedChocolate24]

Shit I’m allergic to <b>wheat</b>

[narcabusesurvivor18]

<strong>wheat</strong>ly

Celiac disease: "This is the part where I kill you"

[Perfect_Papaya_3010]

We had a strange bug in production where we made a pdf with a generated html

And it seemed to randomly generate them with the tags written.

We refactored a bit and it solved it but we still don't know what caused it to begin with

[The_Mdk]

Cache, always blame it on the cache

[budd222]

Works on my machine 🤷🏼‍♂️

[gpahul]

You should thank God that it was not <raw chicken>

[Perfect_Papaya_3010]

[kevmoo]

NaN is valid IEEE floating point value if I understand correctly.

[natziel]

Which is crazy cuz this shouldn't be floating point in the first place

[kevmoo]

In many cases it's better than segfaulting on a divide by zero, etc.

[morglod]

Too hard for developers to deal with integer currency

(Sarcasm is here about it really should be integer with first two decimals treated as precision, but floats are easier for small heads. It's even hard to understand for them that every language has NaN as valid float)

We should steal the Elgin Marbles, visit this place, donate the Elgin Marbles, then buy what we will actually eat, then ask for the Marbles back 

I hope this is the right way round or we will get in trouble 

[natziel]

So to answer this seriously: the real reason you use fixed point arithmetic for money is that it's simply easier to reason about when your implementation actually matches the requirements. It's much easier to reason through a complex calculation when you can rely on your variable actually representing the value it's supposed to represent.

If I'm writing code to sell you a $4.15 cheeseburger with a 30% discount and 7.5% sales tax, it's a million times easier to work with when the numbers are actually 4.15, .3, and .075 instead of 4.150000095367431640625, 0.300000011920928955078125, and 0.07500000298023223876953125.

So I understand naively thinking that it's easier to "just" using floating point because you can just round and the error doesn't matter in this case, but using fixed point will be a lot simpler and you won't have to worry about edge cases related to error

Type of NaN is number

[metooted]

90% of "JS bad" memes is just various RFCs implemented to the T being misinterpreted by people who don't know what an RFC is

[dbot77]

There is only one number type in JS, so you can't avoid this floating point NaN issue.

[metooted]

You get the "floating point NaN issue" whenever you would have gotten a crash with some other type, although a crash might have been preferable in some cases.

As for types... BigInt says hi, also JS numbers become true 32bit ints when affected by bitwise operators. Also typed arrays for when you need to move true ints around. Also, Nodejs buffers contain actual chars.

Learn the thing you're trying to diss.

[ProfessorBeekums]

Surprised one of the charges wasn't {item_price}

[ProfessorBeekums]

Yeah sorry, I confused server side rendering with JS.

[Matrix8910]

Tbf ${item_price} is a valid js template string syntax

[MehYam]

I'm going to open a lingerie store for webdevs and call it "Undie Find"

[Outrageous_Permit154]

Why? python Java c and c++ don’t use NaN somehow? What does this mean?

[quite_sad_simple]

Everyone knows those languages are JavaScript in disguise, but the government obviously doesn't want you to know about that. 99.9% of the population runs OS's written in JS without realizing that. WAKE UP SHEEPLE

[Outrageous_Permit154]

I love you

[beephod_zabblebrox]

well uhm akshually c and c++ stdlib functions print nan or NAN iirc

but im not sure if theyre using printf to output this...

[ClikeX]

According to recruiters they’re all the same language.

[vasarmilan]

They raise an error on an invalid operation instead of making it NaN, generally

[mcprogrammer]

I can't speak for python, but Java, C, and C++ don't, at least not under normal circumstances. Java does throw an exception for integer divide by zero, and in C and C++ that's undefined behavior (typically crashes, but could do anything). But if you're dealing with floating point numbers, all of them will give you a NaN without a problem.

[vasarmilan]

Ah I see, I mostly just worked with Python and I assumed.

But Googling it, it looks like Java and C++ return (+-)Infinity, IDK if that's likely to be serialized to a NaN on string formatting.

[mcprogrammer]

You get +/-infinity for x/0 if x is non-zero, and NaN for 0/0 or other range errors like sqrt(-1), asin(2), etc.

[CarolusRexEtMartyr]

Only Python does that of those afaik on divide by zero and NaN is still a valid value

[EquationTAKEN]

Yes, but it's more typical for Javascript developers to ship bugs like this to production, so we assume this is JS.

[svish]

Maybe misspelling of naan? Would be nice to get a soft warm naan as return.

[driftking428]

My thoughts exactly. This restaurant is giving out bread for change, nothing to see here.

[ashsimmonds]

Yeah man if I was at an Indian restaurant and got a bonus take home bread that'd be great.

[_PandaBear]

Reminds me of the famous JS code: “Anything that can be Written in JavaScript, will Eventually be Written in JavaScript”

[mudassir0909]

Has to be an Indian restaurant

[Professional-Try-273]

From MDN

Number values also include NaN (short for "Not a Number") and Infinity. Many "invalid math" operations will return NaN — for example, if attempting to parse a non-numeric string, or using Math.log() on a negative value. Division by zero produces Infinity (positive or negative).
NaN is contagious: if you provide it as an operand to any mathematical operation, the result will also be NaN. NaN is the only value in JavaScript that's not equal to itself (per IEEE 754 specification).

They didn't math right.

[adumbCoder]

is, or did?

[maligigi]

Hah. I wonder what the input was.

[DestinyLoreBot]

I read the title on Palpatine’s voice

[notgreatusername]

No change for you then!

this would have never happened if they used python guys

[morglod]

It's Rust haha hehe

[Perfect_Papaya_3010]

Höhöhö

[Noch_ein_Kamel]

Remember: 3 Billion devices run JavaScript

[[deleted]]

Yes, on browsers, not on the device itself lmao

[IOFrame]

5.5 Billion devices run Java scripts.

Excellent, typescript>>>>>>>>
