entries < Map < JavaScript

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

    
    const map = new Map();

    map.set('0', 'foo');
    map.set(1, 'bar');

    // iterator object
    const iterator = map.entries();

    console.log(iterator.next().value);
    // ["0", "foo"]

    console.log(iterator.next().value);
    // [1, "bar"]
