Sprint-3/2-mandatory-rewrite/1-get-angle-type.test.js

+test("should identify Reflex angle", () => {
+  expect(getAngleType(181)).toEqual("Reflex angle");
+});


We could specify multiple expect(...) statements within each test() to cover multiple values that belong to the same case. For example,

test("should identify Reflex angle", () => { expect(getAngleType(181)).toEqual("Reflex angle"); expect(getAngleType(359.999)).toEqual("Reflex angle"); expect(getAngleType(270)).toEqual("Reflex angle"); });

I've added more expect statements to reflex angle and obtuse angle tests

Sprint-3/2-mandatory-rewrite/3-get-card-value.js

-function getCardValue(card) {
-    // replace with your code from key-implement
-    return 11;
+function getCardValue(rank) {
+  if (rank === "A") return 11;
+  if (rank === "A♠") return 11;
+  if (rank === "2") return 2;
+  if (rank === "3") return 3;


I think "card" is expected to be a string in the forms "10♠", "K♣", "2♥", "A♦", "13♦". That is, it always ends with a suite character. (Note: The rank of the card "13♦" is invalid).

Can you update your function so that it can extract the rank from the parameter?

Updated tests to include rank. the function now slices the rank character from the card input before performing computations

cjyuan · 2025-06-16T16:28:23Z

Sprint-3/2-mandatory-rewrite/3-get-card-value.js

+  if (rank === "9") return 9;
+
+  if (rank === "10" || rank === "J" || rank === "K" || rank === "Q") return 10;
+  else return "Invalid card rank";


The instructions in Sprint-3/1-key-implement/3-get-card-value.js state
"Given a card with an invalid rank ... the function should throw an error indicating "Invalid card rank."

Throwing an error is not the same as returning an error message.

Could you look up "How to throw an error in JS" and update your code accordingly?

updated the function to throw an error upon invalid card input

cjyuan · 2025-06-16T16:35:10Z

Sprint-3/2-mandatory-rewrite/3-get-card-value.test.js

+test("should return invalid card rank for unknown cards", () => {
+  const InvalidCard = getCardValue("22");
+  expect(InvalidCard).toEqual("Invalid card rank");
+});


To test if a function can throw an error as expected, we could use .toThrow(). You can find out more about how to use .toThrow() here: https://jestjs.io/docs/expect#tothrowerror (Note: Pay close attention to the syntax of the example)

updated the function to throw an error upon invalid card input

Sprint-3/4-stretch-investigate/card-validator.js

cjyuan · 2025-06-16T18:02:31Z

Sprint-3/4-stretch-investigate/find.js

 // b) What is the if statement used to check
+// when index reaches desired char return it
 // c) Why is index++ being used?
+//idex++ is being used to add 1 to the value of index


I think the question is asking, why increment index by one?

I've answered the question correctly and explained what index++ is used to do

Sprint-3/4-stretch-investigate/password-validator.js

cjyuan · 2025-06-16T18:19:34Z

Sprint-3/4-stretch-investigate/password-validator.test.js

+  const password = "12345";
+  // Act
+  const result = isValidPassword(password);
+  // Assert
+  expect(result).toEqual(false);


This test does not quite match the description, "password has at least 5 characters".

added valid tests cases and have incorporated edge cases

cjyuan · 2025-06-16T18:25:54Z

Sprint-3/4-stretch-investigate/password-validator.test.js

+test("password has a number,special symbol, upper and lower case and is 5 char long", () => {
+  const password = "ZaR!0";
+  const result = isValidPassword(password);
+  expect(result).toEqual(true);
+});


This test checks only if the function can accept a valid password; it does not check if the function can reject invalid passwords such as "ABC4abc", "ABC$abc".

… function well

cjyuan

Your changes look good. I only have a few more suggestions.

Well done!

Sprint-3/2-mandatory-rewrite/3-get-card-value.js


-  if (rank === "10" || rank === "J" || rank === "K" || rank === "Q") return 10;
-  else return "Invalid card rank";
+  const card = rank.slice(0, -1); // removing last character to get card rank


card is the name of the original parameter and is supposed to include both the rank and the suit of a card.
rank is part without the suit.

cjyuan · 2025-06-17T23:13:08Z

Sprint-3/2-mandatory-rewrite/3-get-card-value.test.js


-test("should return 11 for Ace of Spades", () => {
-  const aceofSpades = getCardValue("A♠");
-  expect(aceofSpades).toEqual(11);
+test("should return 11 for Ace of Spade", () => {
+  expect(getCardValue("A♠")).toEqual(11);


Is this test any different from test at lines 20-21?

cjyuan · 2025-06-17T23:24:04Z

Sprint-3/4-stretch-investigate/password-validator.test.js

To be more comprehensive, we could set up tests that check if the function can correctly reject a password that fails only one of the following requirements:

Have at least 5 characters.

Have at least one English uppercase letter (A-Z) (You have a test the checks this)

Have at least one English lowercase letter (a-z)

Have at least one number (0-9)

Have at least one of the following non-alphanumeric symbols: ("!", "#", "$", "%", ".", "*", "&")

Must not be any previous password in the passwords array. (You have a test that checks this)

cjyuan · 2025-06-17T23:27:32Z

Sprint-3/4-stretch-investigate/password-validator.test.js

-test("password has a number,special symbol, upper and lower case and is 5 char long", () => {
+// password without upper case letter
+test("password fails, contains no uppercase letter", () => {
+  expect(isValidPassword("abcdef!")).toEqual(false);


If we were to check if the function can correctly reject a password without an uppercase letter, we should pick a password that meets all other requirements except that it does not contain an uppercase letter.

Because "abcdef!" does not contain any digit or uppercase letter, the function could have returned false because the password does not have a digit.
