A JavaScript Set is a group of distinct values. In a Set, each value can only appear once. Any value of any data type can be stored in a Set.
If a set has all elements of Set A and all elements of Set B, but no duplicate elements, it is said to be a union of two sets. If an element appears in both Set A and Set B, the union of the two sets will contain a single copy of the element.
Set allows you to store unique values of any type, including primitive values and object references.
Union creates a new Set that contains all of the elements from both sets.
Intersection creates a new Set with components from both sets.
Set A — Set B will return elements from Set A that aren't in Set B.
