JavaScript WeakSet Object

 

Syntax


Code

new WeakSet([iterable])


Parameter

iterable - It represents the iterable object whose elements will be added to a new WeakSet.

Points to remember

  • A WeakSet object contains unique objects only.
  • In WeakSet, if there is no reference to a stored object, they are targeted to garbage collection.
  • In WeakSet, the objects are not enumerable. So, it doesn't provide any method to get the specified objects.
