    Here’s a function that will do it for you.

    function addMonth(date, numMonthsToAdd) {
  const newDate = new Date(date.setMonth(date.getMonth() + numMonthsToAdd));

  return newDate;
}

    This should add 1 more month to you Date:

    function addOneMonth(date) {
  const newDate = new Date(date.setMonth(date.getMonth() + 1));

  return newDate;
}

    I feel getMonth should solve your problem assuming the input date is a date-type variable. Just wrote a sample code for the same.

    let inputDate = new Date();

function addMonth(date) {
  const newDate = new Date(date.setMonth(date.getMonth() + 1));

  return newDate;
}

inputDate = addMonth(inputDate)

console.log('input date', inputDate)
