better to go that way than this (note the weekly downloads)

[-] Bumblefumble@lemm.ee 56 points 1 year ago* (last edited 1 year ago)

The best part is the dependency on the function is_odd.

[-] jonwyattphillips@lemmy.ml 44 points 1 year ago* (last edited 1 year ago)

Which itself has a dependency of the function is_number.

Can't even or can't odd? If only there was a way to find out =/

The efficient use of memory is an efficient use of memory.

dear Lord lmfao

[-] spez@sh.itjust.works 2 points 1 year ago

That is one deep rabbit hole.

If I was a JS programmer, I'd just write a bash script to download it every week for fun.

[-] TonyTonyChopper@mander.xyz 12 points 1 year ago

300,000 every week... is this really a feature not built into Java Script?

x % 2 == 0

[-] marcos@lemmy.world 28 points 1 year ago
(+x) % 2 == 0

If you forget for a second it's Javascript, the language will turn back and bite you.

[-] Kindness@lemmy.ml 8 points 1 year ago

(+x) % 2 === 0

[-] FiskFisk33@startrek.website 5 points 1 year ago

I am not good friends with js, what did I miss?

[-] mindbleach@sh.itjust.works 14 points 1 year ago

JS is a language where [1,2,11].sort() returns [1,11,2].

And if you use a variable instead of a bare array, half the functions are side-effectful, as determined by coin toss.

And if you try declaring that variable with new Array(3).map() then it will ignore all 3 indices, because undefined is real enough to be enumerated, but not real enough to be iterated, because, and I cannot overstress the importance of this principle in Javascript, go fuck yourself. Go fuck yourself is why.

[-] PoolloverNathan@programming.dev 5 points 1 year ago

Array(3) doesn't create [undefined, undefined, undefined, ]; it creates [/* hole */, /* hole */, /* hole */, ]. The holes don't set any property on the array whatsoever, so they are skipped when iterating. How this makes sense, I can't tell you.

[-] mindbleach@sh.itjust.works 4 points 1 year ago

Yet the array contains exactly three nothings.

It's like a zen koan.

Time is a flat circle

[-] Kindness@lemmy.ml 5 points 1 year ago

typeof(null) == 'object'

Because some people think planning an entirely new language should take less than 2 weeks. 10 days, in this case.

See wat for more.

We wrote it wrong on purpose, as a joke.

[-] mindbleach@sh.itjust.works 1 points 1 year ago

The Wimp Lo doctrine is a valid theory for why JS is Like That.

If there's two ways to do something, JS picks all three.

[-] marcos@lemmy.world 7 points 1 year ago

This evaluates to NaN for some reason:

'10' % 0

Since JS doesn't really differentiate strings from numbers, except on the places it does, it makes sense to make sure you are working with numbers.

[-] FiskFisk33@startrek.website 2 points 1 year ago* (last edited 1 year ago)

Oh right that. I guess I was visualizing a scenario where you already checked for it being a number, such as a Number.isInteger(x)

also, that suprises me a lot, you'd think this is one of the places where it treats stuff as numbers

Not a JS dev either but ===.

Not really sure what the (+x) is about

[-] FiskFisk33@startrek.website 1 points 1 year ago

the remainder operator should return a number or a NaN right? do we actually need the triple here?

[-] marcos@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

Not really. But with JS it's better safe than sorry.

The GP's addition is unnecessary, but I fully support anyone that decides to do it.

[-] FiskFisk33@startrek.website 2 points 1 year ago

point taken!

[-] affiliate@lemmy.world 3 points 1 year ago
[-] marcos@lemmy.world 6 points 1 year ago

It makes sure x is a number.

[-] affiliate@lemmy.world 9 points 1 year ago

what a wonderful and beautiful language. i’m so glad i asked

[-] ArtVandelay@lemmy.world 1 points 1 year ago

And so wonderfully similar to the way that symbol is used in other languages as well. Gosh darn it I love JavaScript

[-] Oszilloraptor@feddit.de 8 points 1 year ago

the is_even package does not provide much worth indeed because it simply negates is_odd and thereby all its benefit.

It's dependency is_odd on the other hand provides at least some additional checks (it also checks if the value is a valid integer below the max int value)

And while I would indeed see uses for such methods (especially with the other checks, no simple oneliners) in some cases, especially in testing: This is stuff you write yourself, throw it in a e.g. NumberUtils class and everything is fine. You do never depend on an external library for that. The benefit (not spending a few seconds to write it) does not outweigh any of the drawbacks that come with external libraries.

Damn bro I haven’t seen this meme format in over 20 years! Hopefully you don’t spend all that time debugging those proprietary functions ya goof

[-] cantstopthesignal@sh.itjust.works 31 points 1 year ago* (last edited 1 year ago)

I'm just an old fart programming a neopixel as a hobby.

[-] Asidonhopo@lemmy.world 18 points 1 year ago* (last edited 1 year ago)

Make it faster and jankier with precalculated lookup tables!

[-] cantstopthesignal@sh.itjust.works 14 points 1 year ago

Make it even jankier with uncalculated variables.

[-] LostXOR@fedia.io 3 points 1 year ago

Screw calculating values for variables, just initialize it pointing to a random memory address and get a value for free! (Assuming your program doesn't segfault).

[-] Hackerman_uwu@lemmy.world 4 points 1 year ago

Vintage meme indeed.

This dude always looked like a college aged Gregory House to me.

[-] OldWoodFrame@lemm.ee 10 points 1 year ago

What a refreshing meme use. Makes me want a beer actually.
