JavaScript 中的对象到 Map 转换

假设，我们有一个像这样的对象 −
const obj = {
name: "Jai",
age: 32,
occupation: "Software Engineer",
address: "Dhindosh, Maharasthra",
salary: "146000"
};
我们需要编写一个 JavaScript 函数，该函数接收带有键值对的此类对象并将其转换为 Map。
示例
其代码为 −
const obj = {
name: "Jai",
age: 32,
occupation: "Software Engineer",
address: "Dhindosh, Maharasthra",
salary: "146000"
};
const objectToMap = obj => {
const keys = Object.keys(obj);
const map = new Map();
for(let i = 0; i < keys.length; i++){
//在 map 中插入新的键值对
map.set(keys[i], obj[keys[i]]);
};
return map;
};
console.log(objectToMap(obj));
输出
控制台中的输出 −
Map(5) {
'name' => 'Jai',
'age' => 32,
'occupation' => 'Software Engineer',
'address' => 'Dhindosh, Maharasthra',
'salary' => '146000'
}
