鸿蒙中禁止使用for...in方法 那要如何循环查询对象属性

const obj = {a: 1, b: 2, c: 3};
const keys = Object.keys(obj);
keys.forEach(key {
    console.log(key + ': ' + obj[key]);
});

const obj = {a: 1, b: 2, c: 3};
const values = Object.values(obj);
values.forEach(value {
    console.log(value);
});

const obj = {a: 1, b: 2, c: 3};
const entries = Object.entries(obj);
entries.forEach(([key, value]) => {
    console.log(key + ': ' + value);
});
