values() は Map インスタンスのメソッドで、この Map オブジェクトに挿入された要素の値を挿入順に列挙する新しいイテレーターオブジェクトを返します。

const map1 = new Map();

map1.set("0", "foo");
map1.set(1, "bar");

const iterator1 = map1.values();

console.log(iterator1.next().value);
// Expected output: "foo"

console.log(iterator1.next().value);
// Expected output: "bar"

なし。

新しい反復可能なイテレーターオブジェクトです。

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"
