    It can’t be anything other than B, right?

    Definitionally in IEEE floating point, NaN is not equal to anything, including itself. The only real abomination here is B:

    > Math.min()
    Infinity
    > Math.max()
    -Infinity

      I mean, B does make some amount of sense, if you realize that it’s supposed to give you the maximum among the parameters (so you’d normally call it as Math.max(5, 3) === 5).

      Well, and you can call that with zero parameters, because you can spread an array into it, which might have zero length. And then given these conditions, and if you don’t want to throw an error, then -Infinity is kind of the least bad remaining option, as it’s likely to generally work with the rest of your logic.

        I love javascript. It’s so insane in such fun ways to prevent itself from throwing errors. It’s got like a naive cute charm to it ya know?

        thats how we often do it in math. The minimum over the empty set is ∞

    is D two single quotes, or one double quote?

      I’m guessing single quotes, since a single double quote isn’t valid syntax.

        Yeah, not even JavaScript is that insane!
