yes, it is not needed - explicit vs implicit choice.

As i thought :)

No, it's not needed.

But is coercing it into a boolean needed, since javascript accepts truthy and falsy values?

The first coerces it to a boolean and the second reverts it to the proper value.

Why are you using double negation in this one? Double negation implies the boolean itself.

!!x === x

Seems great

Thanks, updated.

Thanks :) will mark as resolved.

Thank you guys, sorry about this, I have shortened the description to make it clearer. Do you think it is better now?

Yep, It's vice versa at this moment.

I'm sorry but the description is really subpar.
