javascript - Javascript将数组与数组对象合并

var authors = [
             {authorIndex:1,    author:"John Steinbeck"},
             {authorIndex:2,    author:"Franz Kafka"},
             {authorIndex:3,    author:"J. R. R. Tolkien"},
             {authorIndex:4,    author:"Charles Dickens"}];
var books = [
    {title:"The Grapes of Wrath",authorIndex:4,pubYear:1936},
    {title:"The Hobbit",authorIndex:2,pubYear:1937},
    {title:"The Trial",authorIndex:1,pubYear:1937},
    {title:"A Tale of Two Cities",authorIndex:3,pubYear:1859}];

我想做的是在书中插入作者并与authorsIndex联系

最佳答案

    const result = authors.map(val => {
        return Object.assign({}, val, books.filter(v => v.authorIndex === val.authorIndex)[0]);
        console.log(result);
    });
    console.log(result);

这将使作者和书籍组合在一起
