Map.prototype.entries() - JavaScript | MDN

Baseline Widely available

The entries() method of Map instances returns a new map iterator object that contains the [key, value] pairs for each element in this map in insertion order.

const map1 = new Map();

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

const iterator1 = map1.entries();

console.log(iterator1.next().value);
// Expected output: Array ["0", "foo"]

console.log(iterator1.next().value);
// Expected output: Array [1, "bar"]

None.

A new iterable iterator object.

const myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

const mapIter = myMap.entries();

console.log(mapIter.next().value); // ["0", "foo"]
console.log(mapIter.next().value); // [1, "bar"]
console.log(mapIter.next().value); // [Object, "baz"]
