如果数组项未在对象数组中列出，则返回值

Question

这是场景。 我有一系列物品：

const memberArray = ["-Lz8YxHbn5iOCxaGUBZt", "-Lz8YxHiwp8QZW3TqAFn", "-Lz8YxHqQXWoaGOFRLrO", -Lz8YxHfasdfsdfGUBZt];

然后我有一个对象数组。

const memberObjects = [
{name: 'john', uid: '-Lz8YxHbn5iOCxaGUBZt'},
{name: 'steve', uid: '-Lz8YxHiwp8QZW3TqAFn'},
{name: 'marcus', uid: '-Lz8YxHqQXWoaGOFRLrO'}
]

如果memberArrays中未列出memberArray中的项目，我需要返回该值。 在上面的示例中：-Lz8YxHfasdfsdfGUBZt未在memberObjects中列出，因此它应该返回。

有什么主意我能做到吗？

Answer 1

这应该做到：

const memberArray = ["-Lz8YxHbn5iOCxaGUBZt", "-Lz8YxHiwp8QZW3TqAFn", "-Lz8YxHqQXWoaGOFRLrO", "-Lz8YxHfasdfsdfGUBZt"];
const memberObjects = [
    {name: 'john', uid: '-Lz8YxHbn5iOCxaGUBZt'},
    {name: 'steve', uid: '-Lz8YxHiwp8QZW3TqAFn'},
    {name: 'marcus', uid: '-Lz8YxHqQXWoaGOFRLrO'}
];
console.log(memberArray.some(o => !memberObjects.some(({uid}) => uid == o)));
