代码示例：

'use strict';

let Tom = {
    name: '汤姆',
    age: 18,
    gender: true,
    height: 1.70,
    grade: null,
    'middle-school': '\"IEEE\" Middle School',
    skills: ['JavaScript', 'C++', 'Python', 'Rust']
};

var s = JSON.stringify(Tom);
console.log(s);

// 格式化输出
var s = JSON.stringify(Tom, null, '  ');
console.log(s);

{"name":"汤姆","age":18,"gender":true,"height":1.7,"grade":null,"middle-school":"\"IEEE\" Middle School","skills":["JavaScript","C++","Python","Rust"]}

{
  "name": "汤姆",
  "age": 18,
  "gender": true,
  "height": 1.7,
  "grade": null,
  "middle-school": "\"IEEE\" Middle School",
  "skills": [
    "JavaScript",
    "C++",
    "Python",
    "Rust"
  ]
