在JavaScript中合并两个字符串映射

Question

在React Native JSX中，如何连接两个这样的字符串映射？

const map1 = { title: 'Avengers: Infinity War', genre: 'Action, Adventure, Fantasy' };
const map2 = { directors: 'Anthony Russo, Joe Russo', stars: ' Robert Downey Jr., Chris Hemsworth, Mark Ruffalo' };

我想要的结果

{ title: 'Avengers: Infinity War', genre: 'Action, Adventure, Fantasy',  directors: 'Anthony Russo, Joe Russo', stars: ' Robert Downey Jr., Chris Hemsworth, Mark Ruffalo' }

感谢您的帮助！

Answer 1

const map1 = { title: 'Avengers: Infinity War', genre: 'Action, Adventure, Fantasy' };
const map2 = { directors: 'Anthony Russo, Joe Russo', stars: ' Robert Downey Jr., Chris Hemsworth, Mark Ruffalo' };

console.log(Object.assign({}, map1, map2));

Object.assign({}, map1, map2);

Answer 2

您可以只使用对象传播...语法：

const mergedMaps = {...map1, ...map2}
