num % 2isn't a boolean result in any of these languages, so I feel like it would always output "odd"Edit: 0 is false, everything else is true.
All of those languages will convert numbers into booleans, 0 is false, all other numbers are true.
Ah that makes sense.
It doesn't make sense. I understand it, but it doesn't make sense.
I agree. If anything it should check if there is a nuumber and 0 is clearly a number.
In JS at least, there's a concept of truthiness and falsiness.
0,undefined,null, and a few other non-boolean values are treated asfalseif used in conditionals and logical operations, while every other value is treated astrue. I'm pretty sure python has something similar.It does. Empty collections, 0, None
The joys of dynamic typing.
You'd be surprised.
But seriously, numbers can be used as booleans in an impressive number of languages. Including machine code for almost every machine out there.
In JS 0 is the same as False
They are not the same, but 0 can be implicitly converted to false.
What do you get if you do: 0 === false
Explosion?
