Or, as a functional expression, rather than a statement with side effects:
<lang JavaScript>(function () {
// hanoi :: n -> s -> s -> s -> [[s, s]]
function hanoi(n, a, b, c) {

Line 1,725 ⟶ 1,726:
).concat(hanoi(n - 1, c, b, a)) : [];
}
return hanoi(3, 'left', 'right', 'mid')
.map(function (d) {
return d[0] + ' -> ' + d[1];
});
})();</lang>
