7. Advanced Selectors
Selectors are pretty powerful. A localizer can use any builtin
explicitly and select a string variant depending on its output. In case of
available-users entity, we used the
and select the variant of the string depending on its output.
Explicit values can be used in the
PLURAL selector example to specify
a special case for when there are no unread emails.
Additionally, the code specifies the default variant to be used if none of
the others match. It's denoted with a
* operator in front of
the variant name.
