2014 10 07 true equals false

So, !! converts a value to a boolean and ensures a boolean type.

    !!false // --> false
    !!true // --> true

Ok, that makes sense. What about strings?

    !!"false" // --> true
    !!"true" // --> true

Weird. But wait, does this mean...

    !!"false" == !!"true" // --> true

I bet if we also compare the type at least...

    !!"false" === !!"true" // --> true

Then again...

    !!false == !!true // --> false

..., but...

    !!"false" == !!true // --> true
    !!"false" === !!true // --> true
