Question

If at all possible, without JavaScript libraries or lots of clunky code I am looking for the simplest way to format a date two weeks from now in the following format:

<

Answer 1

function getSuffixForDate(day) {
  const lastNumberOfTheDay = day[day.length];

  const suffixes = {
    1: () => 'st',
    21: () => 'st',
    31: () => 'st',
    2: () => 'nd',
    22: () => 'nd',
    3: () => 'rd',
    23: () => 'rd',
  };

  return suffixes[lastNumberOfTheDay] !== undefined ? `${day}${suffixes[lastNumberOfTheDay]()}` : `${day}th`;
}

const date = new Date();
const formattedDate = `${getSuffixForDate(date.getDate())} ${monthNames[date.getMonth()]} ${date.getFullYear()}`;

A human readable version...
