Parameters
- value: T
Returns this
clear
delete
- delete(value): boolean

Parameters
- value: T
Returns boolean
Returns true if an element in the Set existed and has been removed, or false if the element does not exist.
entries
- entries(): SetIterator<[T, T]>
Returns an iterable of [v,v] pairs for every value
vin the set.Returns SetIterator<[T, T]>
forEach
has
- has(value): boolean
Parameters
- value: T
Returns boolean
a boolean indicating whether an element with the specified value exists in the Set or not.
keys
