let jsonArray = [
  {"name": "John", "age": 30},
  {"name": "Jane", "age": 28},
  {"name": "Tom", "age": 35}
];

let objArray = [
  {name: "John", age: 30},
  {name: "Jane", age: 28},
  {name: "Tom", age: 35}
];

let jsonArray = JSON.stringify(objArray);
console.log(jsonArray);
// 输出：'[{"name":"John","age":30},{"name":"Jane","age":28},{"name":"Tom","age":35}]'

let jsonArray = [];

for (let i = 0; i < 3; i++) {
  let obj = {};
  obj.name = "User" + i;
  obj.age = 20 + i;
  jsonArray.push(obj);
}

console.log(jsonArray);
// 输出：[{name:"User0",age:20}, {name:"User1",age:21}, {name:"User2",age:22}]
