What are advanced set methods in JavaScript?
Advanced set methods in JavaScript include methods like add()
, delete()
, and has()
that allow for efficient data management.
Can you explain how the add()
method works?
Sure! The add()
method adds a new element to a Set object. If the element already exists, it won't be added again.
What about the delete()
method?
The delete()
method removes a specified element from a Set. It returns true
if the element was successfully removed.
Are there any other useful methods I should know about?
Yes! The clear()
method removes all elements from a Set, and the size
property returns the number of elements in the Set.
