Alternatively, in a functional style of JavaScript, we can define the ancient song "strPrepn the lstOrdinal[i] strUnit of strHoliday" as an expression, and return that expression in a human-legible and machine-parseable JSON string translation, for further analysis and processing :-)
JSON.stringify(
(function (
strPrepn,
strHoliday,
strUnit,
strRole,
strProcess,
strRecipient

seventh eighth ninth tenth eleventh twelfth'
.split(/\s+/),

.split(/\s{2,}/),
lstReversed = (function () {
var lst = lstGoods.slice(0);
return (lst.reverse(), lst);
})(),
strProvenance = [strRole, strProcess, strRecipient + ':'].join(' '),
strPenultimate = lstReversed[lngUnits - 2] + ' and',
strFinal = lstGoods[0];
return lstOrdinal.reduce(
function (sofar, day, i) {
return sofar.concat(

strPrepn,

Note that the Google Closure compiler's translation of this would be half the size, but rather less legible. (It does make interesting suggestions though – the semi-colon segmentation of the verses below is a trick that might be worth remembering).
JSON.stringify(function (h, k, l, f, m, n) {

.split(" "),

Pascal
This should work with any modern Pascal implementation that has a string type, e.g. Free Pascal.
program twelve_days(output);
const
days: array[1..12] of string =
( 'first', 'second', 'third', 'fourth', 'fifth', 'sixth',
'seventh', 'eighth', 'ninth', 'tenth', 'eleventh', 'twelfth' );

Racket
This version:
- doesn't capitalise the word Twelfth
- capitalises the French (in French hen)
- capitalised True Love as it may save me a lot of grief when I get home.
- British Variant: changes golden to go-old rings. Anyone who still has enough breath left to sing the second syllable after sustaining the first syllable of golden simply wasn't making enough effort in the first place.
- British Variant: capitalises FIVE GO-OLD RINGS since it needs to be sung at top volume. If you want to change this back; the source is there. But I guarantee you won't have as much fun singing it.
