Use .map() method to iterate over testArr and transform its elements and use .filter() method on the options array in each object, to filter out the empty strings.

const testArr = [
  { code: 'size', name: 'Size', options: ['small', "", "", "large"] },
  { code: 'color', name: 'COlor', options: ['black', "", "", "red"] }
];

const result = testArr.map(obj => {
  obj.options = obj.options.filter(s => s.trim().length > 0);
  return obj;
});

console.log(result);
