nah, it's more fun this way.
I'm no expert and I know that javascript is full of wtf moments, but please.. Let it be B
It's not gong to be B, it's it.
Narrator: "It wasn't B."
It is true. Math.min() returns positive Infinity when called with no arguments and Math.max() returns Negative Infinity when called with no arguments. Positive Infinity > Negative Infinity.
Math.min() works something like this
def min(numbers):
r = Infinity
for n in numbers:
if n < r:
r = n
return r
I'm guessing there's a reason they wanted min() to be able to be called without any arguments but I'm sure it isn't a good one.

It not a totally unreasonable definition. For example it preserves nice properties like min(a.concat(b)) == min([min(a), min(b)])
.
Obviously the correct thing to do is to return an optional type, like Rust does. But ... yeah I mean considering the other footguns in Javascript (e.g. the insane implicit type coersion) I'd say they didn't do too badly here.
