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, 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.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.
