30秒学会 JavaScript 片段 – Convert Map to object

Converts a Map to an object.

• Use Map.prototype.entries() to convert the Map to an array of key-value pairs.
• Use Object.fromEntries() to convert the array to an object.

代码实现

const mapToObject = map => Object.fromEntries(map.entries());

mapToObject(new Map([['a', 1], ['b', 2]])); // {a: 1, b: 2}
