The Set.entries() method returns a new Iterator object that contains an array of [value, value] for each element in the Set object, in the order of their insertion. Although a Set does not contain key-value pairs, to keep similarities with the map.entries() method, it will return key-value pairs where both key and value will have the same value.
Syntax:
mySet.entries()
Parameters: This method does not accept any parameters.
Return Value: The entries() method returns a new Iterator object that contains an array of [value, value] for each element in the Set object, in insertion order.
Example 1:
Javascript
let myset = new Set();
myset.add("California");
myset.add("Seattle");
myset.add("Chicago");
const setIterator = myset.entries();
console.log(setIterator.next().value);
console.log(setIterator.next().value);
console.log(setIterator.next().value);
|
Output:
[ 'California', 'California' ]
[ 'Seattle', 'Seattle' ]
[ 'Chicago', 'Chicago' ]
Example 2:
Javascript
let myset = new Set();
myset.add("California");
myset.add("Seattle");
myset.add("Chicago");
const setIterator = myset.entries();
for (const entry of setIterator) {
console.log(entry);
}
|
Output:
[ 'California', 'California' ]
[ 'Seattle', 'Seattle' ]
[ 'Chicago', 'Chicago' ]
