Get rid of displayList

Use new Intl.ListFormat(getLocale(), {style: "long", type: "conjunction"}) instead. Stick it in a utility function.

Been thinking about this one. Using Intl.ListFormat() feels like a good idea and would work well but alone it does not cover the same functionality as your displayLists library function. Notably this part of the logic:

else if (xs.length > n + 2) {
    return `${xs.slice(0, n).join(", ")}, ${conj} ${xs.length - n} others`
  }

Utilizing Intl.ListFormat() the updated logic could look something like this:

export default <T>(xs: T[], conj = "and", n = 6, locale = "en-US") => {
if (xs.length > n + 2) {
  const formattedList = new Intl.ListFormat(locale, { style: "long", type: "conjunction" }).format(xs.slice(0, n));
  return `${formattedList}, ${conj} ${xs.length - n} others`;
}

return new Intl.ListFormat(locale, { style: "long", type: "conjunction" }).format(xs);
}

Do you think it makes more sense to move this logic into the project via a utility function, or update it in your hurdak library method?
