Set

A Set in Scala is a collection that holds unique elements. This means no duplicates are allowed. Sets are useful when you need to ensure that each item is only present once, like a group of unique user IDs or distinct product names. Scala provides both mutable and immutable Set implementations, allowing you to choose the behavior that best fits your needs.
