在react和javascript中，我如何正确地映射这个对象的键值？

const obj = { key1: 'value1', key2: 'value2', key3: 'value3' };

const mappedArray = Object.keys(obj).map((key) => {
  return { key: key, value: obj[key] };
});

console.log(mappedArray);

[
  { key: 'key1', value: 'value1' },
  { key: 'key2', value: 'value2' },
  { key: 'key3', value: 'value3' }
]

const obj = { key1: 'value1', key2: 'value2', key3: 'value3' };

const mappedArray = Object.entries(obj).map(([key, value]) => {
  return { key: key, value: value };
});

console.log(mappedArray);
