If I was a JS programmer, I'd just write a bash script to download it every week for fun.
The best part is the dependency on the function is_odd.
Which itself has a dependency of the function is_number.
I can't
That is one deep rabbit hole.
dear Lord lmfao
300,000 every week... is this really a feature not built into Java Script?

If 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 [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.
Yet the array contains exactly three nothings.
It's like a zen koan.
Time is a flat circle
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.
Not a JS dev either but ===.
Not really sure what the (+x) is about
