The values() method of Map instances returns a new map iterator object that contains the values for each element in this map in insertion order.
const map = new Map();
map.set("0", "foo");
map.set(1, "bar");
const iterator = map.values();
console.log(iterator.next().value);
// Expected output: "foo"
console.log(iterator.next().value);
// Expected output: "bar"
values()
None.
A new iterable iterator object.
const myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");
const mapIter = myMap.values();
console.log(mapIter.next().value); // "foo"
console.log(mapIter.next().value); // "bar"
console.log(mapIter.next().value); // "baz"
