Well, I'll try to test more targeted slices next time to make sure I'm most likely not duplicating the code under test

Ya know, I think it's a bit more difficult for me to write a good property-based test when I don't see the implementation...
In this case I probably basically reimplemented the function under test when normally I would be more cognizant of that and would test a slice of the input space like you did

My solution for today! Got to use some brand new ECMAScript features for it
![const letterArb = fc.record({ id: fc.string() });
test("helping Santa", () => {
fc.assert(
fc.property(fc.array(letterArb), (letters) => {
const deduplicatedLetters = dropLettersFromDuplicatedSenders(letters);
const lettersById = Map.groupBy(letters, ({ id }) => id);
const expectedLetters = Array.from(
lettersById.values(),
(letters) => letters[0]
);
// Manually check length and individual items for reference equality.
expect(deduplicatedLetters.length).toBe(expectedLetters.length);
for (let i = 0; i < deduplicatedLetters.length; i++) {
expect(deduplicatedLetters[i]).toBe(expectedLetters[i]);
}
})
);

Just went ahead and tried it! This worked right away
![const nameArb = fc.stringMatching(/^[a-z]+$/);
const ageArb = fc.integer({ min: 7, max: 77 });
test("helping Santa", () => {
fc.assert(
fc.property(
fc
.tuple(ageArb, fc.array(nameArb))
.map(([age, names]) => [age, names.map((name) => ({ name, age }))]),
([age, letters]) => {
const sortedLetters = sortLetters(letters);
expect(sortedLetters.length).toBe(letters.length);
for (const letter of letters) {
expect(letter.age).toBe(age);
}
for (let i = 1; i < sortedLetters.length; i++) {
const previousLetter = sortedLetters[i - 1];
const currentLetter = sortedLetters[i];
// Failed here!
expect(previousLetter.name <= currentLetter.name).toBe(true);
}
}
)
);
