Set.prototype.entries()

The entries() method returns a new Iterator object that contains [value, value] for each element in the Set object, in insertion order. For Set objects there is no key like in Map objects. However, to keep the API similar to the Map object, each entry has the same value for its key and value here, so that an array [value, value] is returned.

Examples

Using entries()

const mySet = new Set();
mySet.add('foobar');
mySet.add(1);
mySet.add('baz');

const setIter = mySet.entries();

console.log(setIter.next().value); // ["foobar", "foobar"]
console.log(setIter.next().value); // [1, 1]
console.log(setIter.next().value); // ["baz", "baz"]
