使用reset賦值的方式解析前端json

test: function () {
    class User {
        id;
        name;
        age;
    }

    let user = new User();
    user.age = 20;
    user.name = 'tom';
    user.id = 1001;

    let json = JSON.stringify(user);
    console.log('json:' + json);
    console.log('bean:' + user);
    console.log('-------------------------------');

    let user2 = new User();
    user2 = {...JSON.parse(json)};
    console.log('json:' + JSON.stringify(user2));
    console.log('id:' + user2.id);
},
