Use the UniqKeys variant to deduplicate common keys.

go
keys := lo.Keys(map[string]int{"foo": 1, "bar": 2})
// []string{"foo", "bar"}

keys := lo.Keys(map[string]int{"foo": 1, "bar": 2}, map[string]int{"baz": 3})
// []string{"foo", "bar", "baz"}

keys := lo.Keys(map[string]int{"foo": 1, "bar": 2}, map[string]int{"bar": 3})
// []string{"foo", "bar", "bar"}
