用JS解析JSON嵌套数组

let jsonStr = '{"name":"John", "age":30, "courses":["Math", "Science", {"name":"English", "teacher":"Mr. Smith"}]}';
let jsonObj = JSON.parse(jsonStr);

console.log(jsonObj.name);  // 输出: John
console.log(jsonObj.courses[0]);  // 输出: Math
console.log(jsonObj.courses[2].name);  // 输出: English
console.log(jsonObj.courses[2].teacher);  // 输出: Mr. Smith

function parseNestedArray(obj) {
  for (let key in obj) {
    if (Array.isArray(obj[key])) {
      parseNestedArray(obj[key]);  // 递归调用处理嵌套数组
    } else {
      console.log(key + ": " + obj[key]);
    }
  }
}

let jsonStr = '{"name":"John", "age":30, "courses":["Math", "Science", {"name":"English", "teacher":"Mr. Smith"}]}';
let jsonObj = JSON.parse(jsonStr);
parseNestedArray(jsonObj);
