The code was very janky, but it worked

Post funny things about programming here! (Or just rant about your favourite programming language.)
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, becauseundefined
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.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.
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.
