How to check one of my object value is empty or not-CodePudding

I need to check my java object value is empty or not. And I need to check this one by one. I crate my code to do this task...But I can't check values one by one. If all of my object value is empty, my code is working...But it can't check values one by one.

const coverDesc = action.data.coverDescriptionLocalization;

Methord 01- :-

 if (Object.values(coverDesc ).every((x) => x === null || x === '')) {
        console.log('Empty');
    } else {
        console.log('Not empty');
    }

Methord 02- :-

for (const key in coverDesc) {
    if (coverDesc.hasOwnProperty(key)) {
        if (Object.values(coverDesc[key]).every((x) => x === null || x === '')) {
           console.log('Empty');
        } else {
            console.log('Not empty');
        }
    }
}

Make sure that you want all the keys which are empty or else want find the particular empty value.

If you want find the value of particular value in all the keys, you can use

Object.keys(array_name).map((el)=>el.(element.particularfield) == '' || el.(element.particularfield) == {});

If you just want to check whether there's a truthy value, you can do:

Object.keys(coverDesc).every((k) => coverDesc[k] === false)

If you need to check specifically for an empty string over null, I would think checking against "" is the best, using the === operator

Object.keys(coverDesc).every((k) => coverDesc[k] === false)
