30秒学会 JavaScript 片段 – Convert object to Map

Converts an object to a Map.

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

代码实现

const objectToMap = obj => new Map(Object.entries(obj));

objectToMap({a: 1, b: 2}); // Map {'a' => 1, 'b' => 2}
