In other languages that shouldn’t be equal either though, right?

Maybe you meant

if (2){
console.log("nonzero ints are truthy")
}
else {
console.log("no they're not")
}

Which would output

nonzero ints are truthy

and that would actually work in all languages I know. But that’s different from being equal.

It’s not. Just tried in my Browser Console:

2 == true // returns false

Mh, ‘0’ is a nonempty string, so !‘0’ returns false. Then of course !(!‘0’) would return true. I’d absolutely expect this, Python does the same.

And the second thing is just JavaScript’s type coercion shenanigans. In Python

bool('0') # returns True because of nonempty string
bool(int('0')) # returns False because 0 == False

Knowing that JavaScript does a lot of implicit type conversions, stuff like that doesn’t strike me as very surprising.
