9-12: Consider a more robust email validation pattern.The current regex is quite basic and may not catch various invalid email formats. Consider using a more comprehensive pattern if stricter validation is needed.
export function isValidEmail(email: string): boolean { - const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/; + const emailRegex = /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/; return emailRegex.test(email); }
14-23: Consider environment-agnostic timeout type.The function uses
NodeJS.Timeoutwhich assumes Node.js environment. Consider using a more generic type for better compatibility across environments.export function debounce<T extends (...args: any[]) => any>( func: T, delay: number ): (...args: Parameters<T>) => void { - let timeoutId: NodeJS.Timeout; + let timeoutId: ReturnType<typeof setTimeout>; return (...args: Parameters<T>) => { clearTimeout(timeoutId); timeoutId = setTimeout(() => func(...args), delay); }; }Note: The debounced function doesn't return the result of the original function, which is typical for debounce implementations but worth being aware of.

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

helper.ts (2)
1-3: LGTM!The function correctly implements string formatting with proper trimming, case conversion, and whitespace replacement. The regex pattern efficiently handles multiple consecutive spaces.
25-31: LGTM!The chunk function is well-implemented with proper generic typing and efficient array slicing. It correctly handles edge cases where array length isn't evenly divisible by chunk size.

Remove calculateSum function - violates organizational standards.
According to organizational documentation, this function should NOT be included in helper.ts because it already exists elsewhere in the codebase. This violates the documented constraint from the "Add TypeScript helper functions" specification.
-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 calculateSum function entirely as
it duplicates existing functionality elsewhere in the codebase, violating
organizational standards. Ensure no references to this function remain in the
file or other parts of the code to maintain consistency with the "Add TypeScript
helper functions" specification.
