determining the exact count of elements.
Checking if an enum is empty should be done by using
Enum.empty?(enum)or
list == []For Enum.count/2: Checking if an enum doesn't contain specific elements should be done by using
not Enum.any?(enum, condition)Check-Specific Parameters
There are no specific parameters for this check.
