Logic negation (NOT operator)

This operator works on boolean values where it inverts their them.

The value of true becomes false and vice versa.

However, in case the input variable is not a boolean value, this operator negates the effect of variable testing. That means empty types or None becomes True and non empty variables becomes False.
