In JavaScript, a weak set is a set that has weak references. If an object in a weak set is deleted outside the weak set declaration, it is also deleted from the weak set. It means that the memory of a weak set can be saved compared to an ordinary set. We also have to notice that the content of a weak set cannot be iterated.
