`entries()` ?方法返回一个新的包含 `[key, value]` ?对的 `Iterator` ?对象，返回的迭代器的迭代顺序与 `Map` 对象的插入顺序相同。

    myMap.entries()

## 示例

### `entries() 的使用`

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

    var mapIter = myMap.entries();

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