Expected Behavior

const getDate = (type, start, value, operator) => {
  start = new Date(start);
  type = type.charAt(0).toUpperCase() + type.slice(1);

  if (operator === '+') {
    start[`set${type}`](start[`get${type}`]() + value);
  } else {
    start[`set${type}`](start[`get${type}`]() - value);
  }

  return start;
};

They have something like this in the repo
