使用javascript使用regexp映射对象键

const obj = {
  FirstName: 'John',
  lastName: 'Doe',
  Age: 30
};

function mapKeysToLowercase(obj) {
  return Object.keys(obj).reduce((result, key) => {
    result[key.toLowerCase()] = obj[key];
    return result;
  }, {});
}

const newObj = mapKeysToLowercase(obj);
console.log(newObj); // { firstname: 'John', lastname: 'Doe', age: 30 }

function cleanAndMapKeys(obj) {
  return Object.keys(obj).reduce((result, key) => {
    const cleanedKey = key.replace(/[^a-zA-Z0-9]/g, '').toLowerCase();
    result[cleanedKey] = obj[key];
    return result;
  }, {});
}

const messyObj = {
  First Name: 'John',
  last-name: 'Doe',
  Age: 30,
  Favorite Color: 'Blue'
};

const cleanObj = cleanAndMapKeys(messyObj);
console.log(cleanObj); // { firstname: 'John', lastname: 'Doe', age: 30, favoritecolor: 'Blue' }
