Remove Empty String Values from an Object in JavaScript-Code Examples

const obj = {
  name: '',
  email: '[email protected]',
  phone: '',
};

// we can use Object.keys(obj) to get an array of the object's keys
// then, we can use the .filter() method to remove any keys whose values are empty strings
const newObj = Object.keys(obj)
  .filter(key => obj[key] !== '')
  .reduce((acc, key) => {
    // finally, we can use .reduce() to turn our array of keys back into an object
    acc[key] = obj[key];
    return acc;
  }, {});

console.log(newObj);
// { email: '[email protected]' }

const obj = {
  name: '',
  age: 0,
  address: '',
};

// using for..in loop
for (const key in obj) {
  // check if the property is an empty string
  if (obj[key] === '') {
    // delete the property
    delete obj[key];
  }
}

// Output: { age: 0 }
console.log(obj);
