Check all the values of an object then if the values is empty it will return what is the key of that empty value?

I have an object store in useState, i just want to find out which of this keys have a value of empty and return the key of that emply value

const [projectInfo, setProjectInfo] = useState({
projectName: '',
projectDescription: '',
projectCreator: '',
})
const [error, setError] = useState({})

const handleCheckValidation = () => {
if(!projectInfo.projectName){
 setError((prevState) => ({
                            ...prevState,
                            projectNameError: true,
                          }))

Thanks!

>Solution :

you can filter the empty value, it will give you array item of empty value,

   const isEmptyValue = Object.keys(projectInfo).filter((item) => projectInfo[item] === '')
    
    output: ["projectName", "projectDescription", "projectCreator"]

or if the object is dynamic, and you are getting it through props or api

const [projectInfo, setProjectInfo] = useState(Object.keys(yourObject).filter((item) => yourObject[item] === ''))
