js如何获取object的值

let obj = {
    name: 'Alice',
    age: 25
};

console.log(obj.name); // 输出: Alice
console.log(obj.age);  // 输出: 25

let obj = {
    'first name': 'Alice',
    age: 25
};

console.log(obj['first name']); // 输出: Alice
console.log(obj['age']);        // 输出: 25

let propName = 'age';
console.log(obj[propName]);     // 输出: 25

let obj = {
    name: 'Alice',
    age: 25,
    job: 'Engineer'
};

let values = Object.keys(obj).map(key => obj[key]);
console.log(values); // 输出: ['Alice', 25, 'Engineer']

let obj = {
    name: 'Alice',
    age: 25,
    job: 'Engineer'
};

let values = Object.values(obj);
console.log(values); // 输出: ['Alice', 25, 'Engineer']

let obj = {
    name: 'Alice',
    age: 25,
    job: 'Engineer'
};

for (let key in obj) {
    if (obj.hasOwnProperty(key)) { // 确保属性属于对象本身
        console.log(obj[key]);
    }
}
