JavaScript中的对象到映射的转换
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，该函数接受带有键值对的此类对象并将其转换为Map。
示例
为此的代码将是-
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++){
//在映射内插入新的键值对
map.set(keys[i], obj[keys[i]]);
};
return map;
};
console.log(objectToMap(obj));输出结果
控制台中的输出-
Map(5) {
'name' => 'Jai',
'age' => 32,
'occupation' => 'Software Engineer',
'address' => 'Dhindosh, Maharasthra',
'salary' => '146000'
}
