Remove empty string field from a object contain nested object and array?

Question

I have ask another question, but someone close that question. I really need this answer. That's why I asking another question.

I have a object like following. I have to remove that empty string filed from nested object and also from nested array. How can I remove that.

const obj = {
  name: 'Red Boy',
  price: '350',
  originalPrice: '', // Empty string field
  stock: 20,
  category: {
    name: '', // Empty String field
    subCategory: { name: ''} // Empty String filed 
  },
  weight: '90kg',
  dimensions: {
    width: '50cm',
    height: '', // Empty string filed
    length: '70cm'
  },
  suitable: [
     { name: 'Yoga' },
     { name: '' }, // Empty String filed
     { name: 'Winter' }
  ],
  additionalInfo: [
     { field: 'closure', value: 'Button' },
     { field: 'collar', value: ''} // Empty String Field 
  ]
}

In this hybrid object type you can see some sub-object and also some sub-array. You can also see some field that are not contain any value.(I comment out that filed).

Actually I need to remove that filed. How can I remove that empty string field from above hybrid object type.

Thank you..

My Expected result-

{
  name: 'Red Boy',
  price: '350',
  // Removed
  stock: 20,
  category: {
    name: '', // Empty String field
    // Removed
  },
  weight: '90kg',
  dimensions: {
    width: '50cm',
    // Removed
    length: '70cm'
  },
  suitable: [
     { name: 'Yoga' },
     //Removed
     { name: 'Winter' }
  ],
  additionalInfo: [
     { field: 'closure', value: 'Button' },
     { field: 'collar', //Removed }
     // Here If this two filed is empty then should remove the whole object
     { field: '', value: '' }
     // Then should remove whole '{ field: '', value: '' }'
  ]
}

const obj = {
  name: 'Red Boy',
  price: '350',
  originalPrice: '', // Empty string field
  stock: 20,
  category: {
    name: '', // Empty String field
    subCategory: { name: ''} // Empty String filed 
  },
  weight: '90kg',
  dimensions: {
    width: '50cm',
    height: '', // Empty string filed
    length: '70cm'
  },
  suitable: [
     { name: 'Yoga' },
     { name: '' }, // Empty String filed
     { name: 'Winter' }
  ],
  additionalInfo: [
     { field: 'closure', value: 'Button' },
     { field: 'collar', value: ''} // Empty String Field 
  ]
}

function removeEmptyString(object) {
    Object
        .entries(object)
        .forEach(([key, value]) => {
            if (value && typeof value === 'object')
                removeEmptyString(value);
            if (value && 
                typeof value === 'object' && 
                !Object.keys(value).length || 
                value === null || 
                value === undefined ||
                value.length === 0
            ) {
                if (Array.isArray(object))
                    object.splice(key, 1);
                else
                    delete object[key];
            }
        });
    return object;
}

console.log(removeEmptyString(obj))
