会用对象.键取值
会 JSON 字符串和对象的互相转换
能说出对象和 JSON 字符串的区别
let person = {
name: "张三",
age: 18,
hobbies: ["代码", "篮球"]
};
console.log(person.name);
console.log(person.hobbies[1]);

const ren = JSON.stringify(person);
console.log(ren);

const wu = JSON.parse(ren);
console.log(wu.age);

let person = {
  name: "张三",
  age: 18,
  hobbies: ["代码", "篮球"]
};

console.log(person.name);
console.log(person.hobbies[0]);

let jsonStr = JSON.stringify(person);
console.log(jsonStr);

let parsed = JSON.parse(jsonStr);
console.log(parsed.age);

- [x] 会用 `对象.键` 取值 - [x] 会 JSON 字符串和对象的互相转换 - [x] 能说出对象和 JSON 字符串的区别 ```ts let person = { name: "张三", age: 18, hobbies: ["代码", "篮球"] }; console.log(person.name); console.log(person.hobbies[0]); let jsonStr = JSON.stringify(person); console.log(jsonStr); let parsed = JSON.parse(jsonStr); console.log(parsed.age); ```
