如何在节点或不和谐js中访问“ [[Entries]]”？

尝试访问小于1的键值，但似乎无法通过此[[Entries]]数组。

上面的图像是reaction.users

代码：

                var element = reaction.users[1].key
                console.log(element) //undefined

您必须使用Map.prototype.entries

t = new Map([["680","clientuser"],["272","user"]]);


console.log([...t.entries()][1][0])
//0 is the key and 1 is the value
