A set is a collection of values in which each value can only appear once. Add, delete, has, clear, and size are the main methods. WeakSet:- You can store a group of unique keys using WeakSet objects. Keys in a "weakSet" cannot be primitive types. They can't be made by an array or another set, either.

WeakMap is a Map-like collection that only accepts objects as keys and eliminates them along with their associated value once they are no longer accessible through other means. WeakSet is a Set-like collection that only stores objects and eliminates them when they are no longer available through other means.

WeakSet s are collections of objects only. They cannot contain arbitrary values of any type, as Set s can. The WeakSet is weak, meaning references to objects in a WeakSet are held weakly. If no other references to an object stored in the WeakSet exist, those objects can be garbage collected.

A collection of objects is stored in a WeakSet in JavaScript. It has the same qualities of a set, such as not storing duplicates. The main distinction between a WeakSet and a set is that a WeakSet is a collection of objects rather than values of a specific type.
