我从我的数据库中获取一个对象：例如：

{availability: null
bio: null
category: ""
createdAt: "2020-10-13T13:47:29.495Z"
email: "oznerol@prova.com"
firstName: "Lorenzo"
id: 37
image: null
job: null
lastName: "Del Rosario"
location: ""
password: "$2b$10$J6m71nc8gBXTvEENMwBjt.azNitCsna3LsxaDIUg.B0ztiTm5xFea"
phone: ""
skills: null
updatedAt: "2020-10-13T13:47:29.495Z"
website: ""}

我正在尝试通过此对象映射以将所有null值更改为''.

这是我的代码：

const [userData, setUserData] = useState()

useEffect( ()=>{
    
  const fetchData = async () => {
    const a = await getUserData(userId);//this retuns the object
    const cleanUserData = Object.entries(a).map(([key, value]) =>
      value === null || undefined ? value = '' : value
    ) …
