array/unique

[shannonmoeller]

Self explanatory.

[nickstark]

So, this would defer to native too, right? So it actually returns a function.

var departments = customers.map(plucks('department')).filter(unique());

[shannonmoeller]

Exactly. The returned function would have access to a private array of values to check against.

Arguments:

• Bool, deep object equality
• Function, comparator (could be shared with sorting functions)

depts.filter(unique({
    deep: true,
    comparator: alphabeticEqualityFunc
}))

[shannonmoeller]

I think we should keep this simple and just do a === check, unless a specific comparator is provided as an argument.

depts.filter(unique(deep()));
depts.filter(unique(alphabeticEquality()));
depts.filter(unique(deep(alphabeticEquality())));
