The Set object lets you store unique values of any type, whether primitive values or object references.
Parameters: iterable If an iterable object (such as an array) is passed, all of its elements will be added to the new Set.
The add() method of Set instances inserts the specified value into this set, if it is not already present.
The delete() method of Set instances removes the specified value from this set, if it is in the set.
The difference() method of Set instances takes a set and returns a new set containing elements in this set but not in the given set.
The entries() method of Set instances returns a new set iterator object that contains an array of [value, value] for each element in this set, in insertion order.
The forEach() method of Set instances executes a provided function once for each value in this set, in insertion order.
The has() method of Set instances returns a boolean indicating whether the specified value exists in this Set or not.
The intersection() method of Set instances takes a set and returns a new set containing elements in both this set and the given set.
The isDisjointFrom() method of Set instances takes a set and returns a boolean indicating if this set has no elements in common with the given set.
The isSubsetOf() method of Set instances takes a set and returns a boolean indicating if all elements of this set are in the given set.
The isSupersetOf() method of Set instances takes a set and returns a boolean indicating if all elements of the given set are in this set.
The symmetricDifference() method of Set instances takes a set and returns a new set containing elements which are in either this set or the given set, but not in both.
The union() method of Set instances takes a set and returns a new set containing elements which are in either or both of this set and the given set.
The Symbol.iterator method of Set instances implements the iterable protocol and allows Set objects to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops.
The Set[Symbol.species] static accessor property is an unused accessor property specifying how to copy Set objects.
