var object = {
  description_delivery_1: 'deliveries_2',
  description_delivery_2: 'deliveries_2'
};

Go(object);

function Go(object) {
  Object.keys(object).forEach(function (key) {
    document.getElementById(key).style.display =
      document.getElementById(this[key]).checked ? 'block' : 'none';
  }, object); 
}
