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.
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.
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 =/
That is one deep rabbit hole.
dear Lord lmfao
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
If you forget for a second it’s Javascript, the language will turn back and bite you.
(+x) % 2 === 0
I am not good friends with js, what did I miss?
This evaluates to NaN for some reason:
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.

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.
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.
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
Not a JS dev either but

.Not really sure what the
(+x)
is aboutwhat does the +x do.
It makes sure
x
is a number.what a wonderful and beautiful language. i’m so glad i asked
