Boolean() or !! (double bang, double negation)?

What's the best way to answer the question "true or false?" in JavaScript

JavaScript does not bother you too much with types (at first), which is both a blessing and a cure. But we all know the Boolean type. Boolean variables can either be true or false. Yes or no.

Every value in JavaScript can be translated into a boolean, true or false. Values that translate to true are truthy, values that translate to false are falsy. Simple.

This is about two ways to make that translation.
