In theory, one can use prototype properties to provide default values
for instance properties. In practice, that is not often useful,
because the constructor normally creates all instance properties right
away, assigning default values where necessary. And, with default
parameter values in ES6 that is even easier to do.
As mentioned by Andrea in another thread, another argument against
non-method prototype properties is that they prevent you from freezing
the prototype (because that would make assigning to instance
properties impossible).
inherited properties can be accessors. That's how WebIDL works.
I have no opinion as to whether inherited data properties are a good or
bad idea, though.
