8-10:"explicit"stops auto-fixing on save — confirm this is intended and VS Code ≥ 1.78 is in use
Switchingsource.fixAll.eslintfrom the booleantrueto the string"explicit"means ESLint fixes are not executed automatically on save; they only run when the user explicitly invokes the “Fix all” code action.
• If you still want auto-fix-on-save, use"always"(or revert totrue).
•"explicit"requires relatively recent VS Code versions; older setups will silently ignore it.
Please verify that this behaviour change and version requirement match team expectations.

13-21: Consider making the function more flexible.The function correctly increments the age by 1, but it hardcodes
nameandageproperty. Consider whether these hardcoded values are intentional for specific tests, or if the function should preserve/copy other properties from the input object.If you want a more flexible implementation that preserves existing properties:
function ageOneYear(obj) { - const newObj = { - name: 'Mickey Mouse', - age: obj.age + 1, - email: 'mickey@disney.com', - } - - return newObj + return { + ...obj, + age: obj.age + 1 + } }

Critical: Function mutates input and uses incorrect splice parameters.
The function has two major issues:
- It mutates the original array instead of returning a new one
splice(i, 0, item)inserts the item instead of removing it

original array by creating and returning a new array that excludes the specified
item, and remove the incorrect splice call that inserts the item. Use a method
like filter to return a new array without the item.

5-11: Simplify the boolean logic.The function works correctly but can be simplified by directly returning the boolean result of the comparison instead of using an if-else statement.
function isNumber(thing) { - if (typeof thing === 'number') { - return true - } else { - return false - } + return typeof thing === 'number' }
13-15: Consider edge case handling for invalid inputs.The
toNumberfunction correctly uses theNumberconstructor for conversion. However, consider thatNumber(undefined)returnsNaN,Number(null)returns0, andNumber("")returns0. Depending on the kata requirements, you might want to handle these edge cases explicitly.If stricter validation is needed, consider:
function toNumber(str) { + // Consider adding validation for empty strings or null/undefined return Number(str) }

165-176: Simplify deletion logic.The current approach modifies the array during iteration. Use a cleaner solution with array methods.
function deleteItemAtIndex(arr, idx) { - const tempArray = [] - - for (let i = 0; i < arr.length; i++) { - tempArray[i] = arr[i] - if (i == idx) { - tempArray.splice(idx, 1) - } - } - - return tempArray + return arr.filter((_, index) => index !== idx) }
112-119: Critical: Function returns false prematurely.The function returns
falseimmediately if the first element doesn't match, preventing it from checking the remaining elements.Apply this diff to fix the logic:
function hasItem(arr, item) { for (let i = 0; i < arr.length; i++) { - if (arr[i] == item) { + if (arr[i] === item) { return true - } else { - return false } } + return false }Or use the built-in method:
function hasItem(arr, item) { - for (let i = 0; i < arr.length; i++) { - if (arr[i] == item) { - return true - } else { - return false - } - } + return arr.includes(item) }
135-146: Fix index comparison logic.The function incorrectly compares array values (
arr[i] == arr[idx]) instead of indices, which will replace all elements with the same value as the element at indexidx.Apply this diff:
function replaceItemAtIndex(arr, idx, item) { - const tempArray = [] - - for (let i = 0; i < arr.length; i++) { - tempArray[i] = arr[i] - if (arr[i] == arr[idx]) { - tempArray[i] = item - } - } - - return tempArray + const newArr = [...arr] + if (idx >= 0 && idx < arr.length) { + newArr[idx] = item + } + return newArr }
150-161: Fix array insertion logic.The implementation modifies the array during iteration with
splice, which can lead to incorrect behavior. Use a cleaner approach with array slicing.Apply this diff:
function insertItemAtIndex(arr, item, idx) { - const tempArray = [] - - for (let i = 0; i < arr.length; i++) { - tempArray[i] = arr[i] - if (i == idx) { - tempArray.splice(i, 0, item) - } - } - - return tempArray + return [...arr.slice(0, idx), item, ...arr.slice(idx)] }
179-187: Critical: Function mutates input and uses incorrect splice parameters.The function has two major issues:
- It mutates the original array instead of returning a new one
splice(i, 0, item)inserts the item instead of removing it (should besplice(i, 1))Apply this fix:
function deleteItem(arr, item) { - for (let i = 0; i < arr.length; i++) { - if (arr[i] == item) { - arr.splice(i, 0, item) - } - } - - return arr + return arr.filter(el => el !== item) }

Apply this diff to simplify:

29-35: Specify radix inparseIntcalls.Always provide the radix parameter to
parseIntto avoid unexpected behavior with certain inputs (e.g., strings starting with "0").Apply this diff:

27-33: LGTM with optional simplification.The dynamic property issue has been correctly fixed. The implementation is clear, though it could be condensed.
For a more concise approach:
function makeObject(key, value) { - const newObj = {} - - newObj[key] = value - - return newObj + return { [key]: value } }
44-50: LGTM with optional simplification.The implementation correctly creates a shallow copy. For consistency with other functions in this file, consider using the spread operator.
function addName(obj, name) { - const objectAddName = Object.assign({}, obj) - - objectAddName.name = name - - return objectAddName + return { ...obj, name } }
55-61: LGTM with optional simplification.The implementation correctly creates a copy before deletion. For consistency, consider using the spread operator.
function deleteProperty(obj, key) { - const objectDeleteProperty = Object.assign({}, obj) - - delete objectDeleteProperty[key] - - return objectDeleteProperty + const result = { ...obj } + delete result[key] + return result }
93-101: LGTM with optional simplification.The loop-based approach is correct and easy to understand. For a more concise alternative, consider using
Array.fill().function makeArrayOfItem(item, length) { - const myArray = [] - - for (let i = 0; i < length; i++) { - myArray.push(item) - } - - return myArray + return Array(length).fill(item) }
123-130: Previous issue fixed, but consider simplification.The index validation logic has been corrected. However, the loop is unnecessary since array access is O(1).
function getItemAtIndex(arr, idx) { - for (let i = 0; i < arr.length; i++) { - if (i == idx) { - return arr[i] - } - } - return new Error() + if (idx >= 0 && idx < arr.length) { + return arr[idx] + } + return new Error('Index out of bounds') }

Fix the type checking logic.
The function checks isNumber(a) and isNumber(b) after parsing them with parseInt, but it should check the original parameters before parsing to determine their types.
Apply this diff to fix the logic:
function addStringsOrNumbers(a, b) {
- let num1 = parseInt(a)

- let num3 = num1 + num2

first test the original parameters with isNumber(a) and isNumber(b), then parse
them (e.g., const num1 = parseInt(a); const num2 = parseInt(b)), compute the
sum, and finally return the numeric sum if both original inputs are numbers,
otherwise return the string form of the sum; ensure no type-checking uses the

with leading zeros; update both parseInt(a) and parseInt(b) to include an

Fix missing variable declaration and simplify implementation.
Critical issues:
- Line 99:
newStris missing a declaration (let,const, orvar), creating an implicit global variable - The logic is flawed:
indexstores the comma character (,), not its position, and gets overwritten on each iteration - The implementation is unnecessarily complex for a simple string split operation
Apply this diff to fix:
function splitStringByCommas(str) {
- let index
- for (let i = 0; i < str.length; i++) {
- if (str[i] == ',') {
- index = str[i]
- }
- }
-
- newStr = str.split(index)
-
- return newStr
+ return str.split(',')

In 3-JSKata/2-strings-and-numbers/utilities.js around lines 91 to 102, the
function uses an undeclared variable newStr, misuses index (stores a comma char
not position), and overcomplicates splitting; replace the loop with a direct
split and declare locals: simply return str.split(',') (or assign const parts =
str.split(',') and return parts) to avoid implicit globals and incorrect logic.

1-4: Simplify and verify the function's usage.The function is correct but can be improved:
- Simplification: The intermediate variable
iis unnecessary.- Naming: Variable
iis conventionally used for loop indices, not results.- Missing export: The function isn't exported, so it can't be used elsewhere in the codebase.
Apply this diff to simplify:

funcis not a function (though for kata exercises, this may be acceptable).

Fix property name mismatch between dogs array and destructuring.
The dogs array in Main.jsx uses properties name, breed, and superpower, but this code destructures newName, newBreed, and newSuperpower. This mismatch will cause all Dog components to receive undefined values for their props.
Apply this diff to fix the destructuring:
- {props.dogs.map(({ newName, newBreed, newSuperpower }) => (
- <Dog name={newName} breed={newBreed} superpower={newSuperpower}>
- <img src={'/image/' + { newBreed } + '.png'} />
+ {props.dogs.map(({ name, breed, superpower }) => (
+ <Dog key={name} name={name} breed={breed} superpower={superpower}>
+ <img src={`/image/${breed}.png`} alt={`${name} the ${breed}`} />
</Dog>
))}Note: This also fixes the missing key prop, the object literal bug in the img src, and adds the missing alt attribute.

Fix object literal bug in image src.
The expression { newBreed } creates an object literal, not a string. This will result in the src being "/image/[object Object].png" instead of the intended dog breed path.
The correct syntax (after fixing the property name) should be:
- <img src={'/image/' + { newBreed } + '.png'} />

Inconsistent font configuration.
The body uses Arial, Helvetica, sans-serif as fallback fonts, but:
- Layout.js loads Geist and Geist_Mono fonts from Google Fonts
- Line 11 defines
--font-sans: var(--font-geist-sans)in @theme - The custom fonts are never actually applied to the body
This results in unnecessary font downloads without usage.
Consider one of these solutions:
Option 1: Use the loaded Geist fonts (recommended)
body {
background: var(--background);
color: var(--foreground);
- font-family: Arial, Helvetica, sans-serif;
+ font-family: var(--font-sans);
}Option 2: Remove font loading from layout.js if not needed
Remove the Geist font imports and configurations from ee332_controlsysrevision/app/layout.js if you intend to use system fonts.

In ee332_controlsysrevision/app/globals.css around lines 22 to 26, the body is
set to use system fallback fonts (Arial, Helvetica, sans-serif) while layout.js
loads Geist and Geist_Mono and sets --font-sans to the Geist variable, so the
downloaded Geist fonts are never applied; either update the body to use the
loaded Geist CSS variable (e.g., set font-family to var(--font-sans), with a
sensible fallback) so the imported fonts are actually used, or remove the Geist
font imports and related --font-geist variables from
ee332_controlsysrevision/app/layout.js to avoid unnecessary downloads—apply one
of these fixes consistently across globals.css and layout.js.

1-7: Consider props destructuring and validation.The component structure is clean and follows React 19 best practices (no explicit React import needed). However, consider these improvements:
- Props destructuring for better readability
- Prop validation to catch missing or incorrect prop types
Apply this diff to destructure props:
-export function MainText(props) { +export function MainText({ paragraph }) { return ( <div className="text-block"> - <p className="major-paragraph">{props.paragraph}</p> + <p className="major-paragraph">{paragraph}</p> </div> ) }Optionally, add PropTypes validation (install
prop-typesif not present):import PropTypes from 'prop-types' export function MainText({ paragraph }) { return ( <div className="text-block"> <p className="major-paragraph">{paragraph}</p> </div> ) } MainText.propTypes = { paragraph: PropTypes.string.isRequired }

1-7: Consider semantic HTML and component flexibility.The component is functional but could be improved:
- Semantic HTML: The
<header>element typically contains heading elements (h1-h6), not plain text. Consider using a heading element inside the header.- Props: The component could accept props for the title text to make it more reusable.
Apply this diff to improve semantic HTML and add flexibility:
-export function Main() { +export function Main({ title = "Characteristic Feedback Systems" }) { return ( <div> - <header>Characteristic Feedback Systems</header> + <header> + <h1>{title}</h1> + </header> </div> ) }ee332_controlsysrevision/app/page.js (2)
13-13: Extract long paragraph text to a constant.The paragraph prop contains a long text string that reduces readability.
Consider extracting it to a constant:
+const BLOCK_DIAGRAM_DESCRIPTION = + "A way of representing a control systems (especially when its output feeds back into the input as an error) is through block diagrams. This is a visual way of seeing the relationships between transfer functions and inputs and outputs." + export default function Home() { return ( <div> <div className="justify-self-center"> <Main /> </div> <div className="grid h-56 grid-cols-2 content-around"> - <MainText paragraph="A way of representing a control systems (especially when its output feeds back into the input as an error) is through block diagrams.

<main>element to wrap the main content, which is important for accessibility and SEO.Apply this diff:

14-19: Image path verified—no issues found.The image file exists at the correct location (
public/images/lti-block-diagram.png), and the code correctly references it as/images/lti-block-diagram.pngper Next.js conventions. The aspect ratio concern depends on the actual image dimensions; if the image doesn't display as intended, verify that thewidth={400}andheight={100}props match the actual image dimensions to avoid distortion.
1-3: No Next.js 16 compatibility issues detected.The Image component usage is compatible with Next.js 16.0.1. The code uses only standard props (alt, src, width, height) and does not employ any deprecated properties like
priority. Thepriorityprop has been deprecated in favor ofpreload,loading="eager", orfetchPriority, but your code does not use it. The App Router conventions are correctly applied with theapp/page.jsstructure, and the defaultimages.qualities=[75]configuration is appropriate for the straightforward image usage here.

Button is non-functional.
The "Next Page" button has no onClick handler, so clicking it won't perform any action.
Add an onClick handler or convert this to a Link component if it should navigate:
+import Link from 'next/link'
import Image from 'next/image'
import { Main } from '@/components/Main'
import { MainText } from '@/components/MainText'Then update the button:
<div className="grid h-56 grid-cols-2 content-around">

In ee332_controlsysrevision/app/page.js around lines 23-25, the "Next Page"
button is non-functional because it lacks an onClick handler; either add an
onClick that calls a handler (e.g., handleNextPage) which performs the intended
action (update pagination state or call router.push with the target path), or
replace the button with a Next.js Link component (import Link from 'next/link')
pointing to the next page route; ensure you implement and bind the handler or
import Link at the top and update the JSX accordingly.

Multiline string may introduce unwanted whitespace.
The multiline string for the Points prop will include the newline and leading spaces in the rendered text. This could result in unexpected formatting.
Apply this diff to use a single-line string:

In ee332_controlsysrevision/app/page.js around lines 24 to 27, the Points prop
is currently a multiline JSX string which will include the newline and leading
spaces in the rendered output; change the prop to a single-line string literal
containing the intended text (e.g. "It takes X(s) as the input (or “Cause“) and
produces Y(s) as the output (or “Effect“)" ) so there are no embedded newlines
or leading spaces — update the JSX to pass that single-line string (or use an
explicit trimmed string expression) instead of the current multi-line block.

The Points CSS class is not defined anywhere in your stylesheets.
The component uses className="Points" on line 4, but this class is not defined in ee332_controlsysrevision/app/globals.css (the only stylesheet loaded). The styling will not be applied. Add the class definition to your global stylesheet or use a Tailwind utility class instead.
