使用胸腺叶在javascript中迭代具有嵌套HashMap值的HashMap

// 创建一个嵌套HashMap
const hashMap = {
  key1: {
    nestedKey1: 'value1',
    nestedKey2: 'value2'
  },
  key2: {
    nestedKey3: 'value3',
    nestedKey4: 'value4'
  }
};

// 迭代HashMap
for (const key in hashMap) {
  if (hashMap.hasOwnProperty(key)) {
    const nestedHashMap = hashMap[key];
    console.log(`Key: ${key}`);
    
    // 迭代嵌套的HashMap
    for (const nestedKey in nestedHashMap) {
      if (nestedHashMap.hasOwnProperty(nestedKey)) {
        const value = nestedHashMap[nestedKey];
        console.log(`Nested Key: ${nestedKey}, Value: ${value}`);
      }
    }
  }
}
