I am trying to get the date to render in a nice format. currently rendering like this
I tried
  function getEndDateFromstring(){
    return itinerary.endDate.split('T').slice(-1)[0]
  }
then
{itinerary.name} from {getStartDateFromstring()} to {getEndDateFromstring()}
But it is throwing an error Uncaught TypeError: Cannot read properties of undefined (reading 'split')
