WHY? (not a quiz)

Question

function isFalse() {
return false;
}
console.log(!!isFalse);

I'm sorry for not being more clear, it's not a quiz. It's something I don't understand!
I don't wanna call the function, I just don't understand why is it true?
But if you try "isFalse === true", guess what => false :))

Answer 1

!! is a way of getting the boolean value of an expression.
!!isFalse is true because you are not calling the function and your are getting the boolean value of the function object called "isFalse".
Answer true.
Radu Harangus isFalse === true is false because you are comparing a function and a boolean value. === doesn't allow type coercion so it returns false for 2 different types. !!isFalse === true because you are coercing isFalse to a boolean value(true).
