WalkthroughA new TypeScript helper module has been introduced, providing five utility functions: string formatting, array summation, email validation, function debouncing, and array chunking. All functions are exported for use in other modules. Changes

9-12: Consider strengthening email validation.The current regex is basic and may not catch all edge cases. Consider using a more robust validation approach or a dedicated library for production use.
For a more comprehensive email validation:
export function isValidEmail(email: string): boolean { - const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; + const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; return emailRegex.test(email); }Or consider using a validation library like
validator.jsfor more robust email validation.

Notion:
- The page titled "Add TypeScript helper functions" states that helper functions need to be added in a file called helper.ts, but it specifies that the file should NOT include the function calculateSum because this function already exists elsewhere in the codebase.

1-3: LGTM! Clean string formatting implementation.The function correctly handles trimming, case conversion, and whitespace normalization with a concise implementation.

Remove calculateSum function - organizational constraint violation.
According to the organizational documentation, the calculateSum function should NOT be included in this file because it already exists elsewhere in the codebase.
-export function calculateSum(numbers: number[]): number {
- return numbers.reduce((acc, num) => acc + num, 0);

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In helper.ts around lines 5 to 7, remove the entire calculateSum function
because it violates organizational constraints by duplicating functionality that
already exists elsewhere in the codebase. Simply delete this function from the
file to comply with the guidelines.

🛠️ Refactor suggestion
Add input validation for debounce function.
The function should validate that delay is a non-negative number to prevent unexpected behavior.
export function debounce<T extends (...args: any[]) => any>(
func: T,
delay: number
): (...args: Parameters<T>) => void {
+ if (delay < 0) {
+ throw new Error('Delay must be non-negative');
+ }
let timeoutId: NodeJS.Timeout;
return (...args: Parameters<T>) => {
clearTimeout(timeoutId);
timeoutId = setTimeout(() => func(...args), delay);
};

In helper.ts around lines 14 to 23, the debounce function lacks validation for
the delay parameter. Add a check at the start of the function to ensure delay is
a non-negative number, and throw an error or handle invalid input appropriately
to prevent unexpected behavior.

🛠️ Refactor suggestion
Add input validation for chunk function.
The function should validate that size is a positive integer to prevent infinite loops or unexpected behavior.
export function chunk<T>(array: T[], size: number): T[][] {
+ if (size <= 0 || !Number.isInteger(size)) {
+ throw new Error('Size must be a positive integer');
+ }
const chunks: T[][] = [];
for (let i = 0; i < array.length; i += size) {
chunks.push(array.slice(i, i + size));
}
return chunks;
}🤖 Prompt for AI Agents
In helper.ts around lines 25 to 31, the chunk function lacks validation for the
size parameter, which can cause infinite loops or unexpected behavior if size is
not a positive integer. Add input validation at the start of the function to
check if size is a positive integer, and throw an error or handle invalid input
appropriately to prevent misuse.
