Hey just a small improvement to N something ago example to show/hide plural.

const fromAgo = (date) => {
  const ms = Date.now() - date.getTime();
  const seconds = Math.round(ms / 1000);
  const minutes = Math.round(ms / 60000);
  const hours = Math.round(ms / 3600000);
  const days = Math.round(ms / 86400000);
  const months = Math.round(ms / 2592000000);
  const years = Math.round(ms / 31104000000);
  let ago;

  if(seconds < 60)
    ago = `${seconds} second"`;
  else if (minutes < 60)
    ago = `${minutes} minute`;
  else if (hours < 24)
    ago = `${hours} hour`;
  else if (days < 30)
    ago = `${days} day`;
  else if (months < 12)
    ago = `${months} month`;
  else
    ago = `${years} year`;

  const isSingular = ago.indexOf("1 ") === 0;

  ago += isSingular ? " ago" : "s ago";
  return ago;
}

const createdAt = new Date(2021, 0, 5);
fromAgo(createdAt); // 14 days ago
