Merge two map of strings in JavaScript

Question

In React Native JSX, how can join two map of strings like this?

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' };

The result I want:

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

Thanks for your help!

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);

You can just use the object spread ... syntax:

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