better to go that way than this (note the weekly downloads)
The best part is the dependency on the function is_odd.
Which itself has a dependency of the function
is_number.I can’t
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
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.
300,000 every week… is this really a feature not built into Java Script?

x % 2 == 0
(+x) % 2 == 0If you forget for a second it’s Javascript, the language will turn back and bite you.

I am not good friends with js, what did I miss?
JS is a language where
[1,2,11].sort()returns[].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, becauseundefinedis 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.deleted by creator
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.Yet the array contains exactly three nothings.
It’s like a zen koan.
Time is a flat circle
We wrote it wrong on purpose, as a joke.
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.
This evaluates to NaN for some reason:
'10' % 0Since 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.
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 aboutthe remainder operator should return a number or a NaN right? do we actually need the triple here?
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.
what does the +x do.
It makes sure
xis a number.what a wonderful and beautiful language. i’m so glad i asked
And so wonderfully similar to the way that symbol is used in other languages as well. Gosh darn it I love JavaScript
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.
Lmao

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
I’m just an old fart programming a neopixel as a hobby.
Make it faster and jankier with precalculated lookup tables!
Make it even jankier with uncalculated variables.
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).
Vintage meme indeed.
This dude always looked like a college aged Gregory House to me.
What a refreshing meme use. Makes me want a beer actually.
