Great work, mostly comments on formatting. Let me know if you are stuck on anything

I appreciate your honesty :D

Generally we don't leave a line between the comment and the code the comment is related to

Sprint-1/fix/median.js

+  }
+
+  //Sort the numeric list
+  const sortedList = [...numericList].sort((a, b) => a - b);


Can you explain why [...numericList] is needed? What would happen if I did numericList.sort instead?

because it is better not to change the original array in case I want to use it later in my code. I'm sorting a "copy" of it.

Sprint-1/implement/dedupe.js

@@ -1 +1,13 @@
-function dedupe() {}
+function dedupe(arr) {
+  let result = [];


Does result have to be let here, or can it be const?
Same for item - can it be const?

I got it now. result should be const because the reference to the array doesn't need to be changed. For item in the , it can also be const, as a new item variable is declared for each iteration, because it's not reassigned within a single loop cycle.

ckirby19 · 2025-11-15T12:34:42Z

Sprint-1/implement/dedupe.test.js

 // Given an array with no duplicates
 // When passed to the dedupe function
 // Then it should return a copy of the original array
+test(" Given an array with no duplicates", () => {


No need for the space between " and G

ckirby19 · 2025-11-15T12:41:38Z

Sprint-1/implement/max.test.js

 // Then it should return that number
+test("given an array with 1 number, it returns the number ",() => {;
+  const inputMax1 = [3];
+    const result = findMax(inputMax1);


Formatting: ensure all lines have the same indentation. Same for all tests below

Sprint-1/implement/sum.js

+
+  let onyNumbers = theArray.filter(item => typeof item === 'number');
+
+


Formatting:

Misspelling of onyNumbers

We usually don't leave two empty lines between code like this

ckirby19 · 2025-11-15T12:45:28Z

Sprint-1/implement/sum.js

-function sum(elements) {
+function sum(theArray) {
+
+  let onyNumbers = theArray.filter(item => typeof item === 'number');


Does this need to be let?

No, It can be const because the variable is assigned once with the filtered array.

ckirby19 · 2025-11-15T12:45:54Z

Sprint-1/implement/sum.test.js

 // When passed to the sum function
 // Then it should return that number

+test("given an array with 1 number, it returns the sam number", () => {


Misspelling: sam

Sprint-1/refactor/includes.js

+
+
+function includes(list,target){
+  for (let value of list) {


Does this need to be let?

I start to undestand now these const and let .. i thought let would always give me less risk of error, but I can see the opposite now.

thank you for your reviwes ;)
