Introduction to HashSets

In simple terms, a HashSet is a collection or a group of unique elements. Think of it as a party where everyone has a different name; no two people can have the same name. In coding terms, this means HashSets do not allow duplicate values.

The Difference at a Glance: HashTable vs. HashSet

HashTable is like a dictionary, full of word (key) and definition (value) pairs. In contrast, HashSet is more like a unique-word collector, not bothered about definitions, just the words.
