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 :-)
<lang JavaScript>JSON.stringify(
(function ( strPrepn, strHoliday, strUnit, strRole, strProcess, strRecipient ) { var lstOrdinal = 'first second third fourth fifth sixth\ seventh eighth ninth tenth eleventh twelfth' .split(/\s+/), lngUnits = lstOrdinal.length,
lstGoods = 'A partridge in a pear tree.\ Two turtle doves\ Three french hens\ Four calling birds\ Five golden rings\ Six geese a-laying\ Seven swans a-swimming\ Eight maids a-milking\ Nine ladies dancing\ Ten lords a-leaping\ Eleven pipers piping\ Twelve drummers drumming' .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( [ [ [ // abstraction of line 1 strPrepn, 'the', lstOrdinal[i], strUnit, 'of', strHoliday ].join(' '), strProvenance ].concat( // reversed descent through memory (i > 1 ? [lstGoods[i]] : []).concat( lstReversed.slice( lngUnits - i, lngUnits - 2 ) ).concat( // penultimate line ends with 'and' [ strPenultimate, strFinal ].slice(i ? 0 : 1) ) ) ] ); }, [] ); })( 'On', 'Christmas', 'day', 'my true love', 'gave to', 'me' ), null, 2
);</lang>
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).
<lang JavaScript>JSON.stringify(function (h, k, l, f, m, n) {
var c = "first second third fourth fifth sixth seventh eighth ninth tenth eleventh twelfth" .split(" "), d = c.length, e = "A partridge in a pear tree.;Two turtle doves;Three french hens;Four calling birds;Five golden rings;Six geese a-laying;Seven swans a-swimming;Eight maids a-milking;Nine ladies dancing;Ten lords a-leaping;Eleven pipers piping;Twelve drummers drumming" .split(";"), g = function () { var b = e.slice(0); return b.reverse(), b; }(), p = [f, m, n + ":"].join(" "), q = g[d - 2] + " and", r = e[0]; return c.reduce(function (b, f, a) { return b.concat([[[h, "the", c[a], l, "of", k].join(" "), p].concat((1 < a ? [e[a]] : []).concat(g.slice(d - a, d - 2)).concat([q, r].slice(a ? 0 : 1)))]); }, []);

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

begin
for day := 1 to 12 do begin writeln('On the ', days[day], ' day of Christmas, my true love sent to me:'); for gift := day downto 1 do writeln(gifts[gift]); writeln end
end.</lang>
- Output:
On the first day of Christmas, my true love sent to me: A partridge in a pear tree. On the second day of Christmas, my true love sent to me: Two turtle doves and A partridge in a pear tree.

Here's a version that works in ISO Standard Pascal, albeit with extraneous spaces in the output:
<lang pascal>program twelve_days_iso(output);

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.
