const preparedValues = {}; Object.entries(values).forEach(([key, value]) => { if (!value) { preparedValues[key] = value; } preparedValues[key] = value.toHTML ? value.toHTML() : value; }); code example

Example: foreach key value javascript

const object1 = {
  a: 'somestring',
  b: 42
};

for (let [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
}

// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed
