Below are the list of methods available on WeakSet,
1. add(value): A new object is appended with the given value
2. delete(value): Deletes the value from the collection.
3. has(value): It returns true if the value is present in the collection, otherwise it returns false.
Let's see the functionality of all the above methods in an example,
javascript
1var weakSetObject = new WeakSet();
2
3var firstObject = {};
4
5var secondObject = {};
6// add(value)
7
8weakSetObject.add(firstObject);
9
10weakSetObject.add(secondObject);
11
12console.log(weakSetObject.has(firstObject)); //true
13
14weakSetObject.delete(secondObject);Advertisement
