                                    const obj = {
  a: 1,
  b: undefined
}

// pure functional approach without side-effects
const newObject = Object.keys(obj).reduce((acc, key) =&gt; {
  const _acc = acc;
  if (obj[key] !== undefined) _acc[key] = obj[key];
  return _acc;
}, {})

console.log(newObject)
// Object {a: 1}

Thank you! 5
