[GeoMoose-users] Results Templates - Format Dates

[Dan Little]

While not a totally perfect solution, Javascript's lack of types can be
kinda valuable here:

function normalizeDate(value) {
  const d = new Date(value); // this will do a best guess
  return (new Intl.DateTimeFormat().format(d)); // this will use the user's
locale to format the date
}

That could be used in a pipe to format arbitrary date values. A little
duck-typing/data checking could make it a lot safer.
