Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
The set.keys() method is the same as the values() method. This means it returns the new iterator object that contains the value of each set in the insertion order.
Syntax:
keys()Parameter: This method does not take any parameters.
Return Type: It returns the new iterator object which holds the values in the set.
Example 1: In this example, we will see the use of keys in the set.
let placeSet = new Set();
placeSet.add("America");
placeSet.add("England");
placeSet.add("Chicago");
const setIterator = placeSet.keys();
console.log(setIterator);
Output:
[Set Iterator] { 'America', 'England', 'Chicago' }Example 2: In this example, we will see the keys() method which returns the set iterator.
const set1 = new Set();
set1.add('0');
set1.add(1);
set1.add(1);
const iterator1 = set1.keys();
console.log(iterator1);
Output
[Set Iterator] { '0', 1 }
