WalkthroughA new helper module has been created, introducing five utility functions: string formatting, array summing, email validation, function debouncing, and array chunking. Each function is exported for use in other modules. Changes

9-12:Consider more robust email validation for production use.The current regex provides basic email format validation but may not catch all edge cases. For production applications, consider using a more comprehensive validation library or the built-in browser validation APIs.
For more robust validation, consider:
exportfunctionisValidEmail(email:string):boolean{// More comprehensive regex or use a validation libraryreturn/^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test(email);}
25-31:Add input validation for robustness.The chunk function logic is correct, but consider adding input validation to handle edge cases:
exportfunctionchunk<T>(array:T[],size:number):T[][]{if(size<=0){thrownewError('Chunk size must be greater than 0');}if(!Number.isInteger(size)){thrownewError('Chunk size must be an integer');}constchunks:T[][]=[];for(leti=0;i<array.length;i+=size){chunks.push(array.slice(i,i+size));}returnchunks;}

Notion:
- Document "Add TypeScript helper functions" (https://www.notion.so/23496e76cda180cfac92c22f78edd65b) states that a file called helper.ts should include some TypeScript helper functions but should NOT include the function calculateSum because it already exists elsewhere in the codebase.

1-3:LGTM!Clean implementation for string formatting. The function effectively creates URL-friendly slugs by trimming, lowercasing, and replacing whitespace with hyphens.

Remove calculateSum function - violates organizational standards.
According to the documented organizational constraint, thecalculateSum function should NOT be included in helper.ts because it already exists elsewhere in the codebase. This violates the established architectural guideline.
Remove this function to comply with organizational standards:
-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.

🛠️ Refactor suggestion
Address return type and environment compatibility issues.
The debounce function has a few issues:
- Return value loss: The debounced function returns
voidbut the original function may return a value - Environment assumption:
NodeJS.Timeoutassumes Node.js environment but may be used in browsers
Consider this improved implementation:
exportfunctiondebounce<Textends(...args:any[])=>any>(func:T,delay:number):(...args:Parameters<T>)=>void{lettimeoutId:ReturnType<typeofsetTimeout>;return(...args:Parameters<T>)=>{clearTimeout(timeoutId);timeoutId=setTimeout(()=>func(...args),delay);};}
Note: If you need to preserve the return value, consider implementing a promisified version or document that debounced functions don't return values.
🤖 Prompt for AI Agents
In helper.ts around lines 14 to 23, the debounce function currently returnsvoid, losing the original function's return value, and uses NodeJS.Timeout whichassumes a Node.js environment. To fix this, change the timeoutId type toReturnType<typeof setTimeout> for cross-environment compatibility, and updatethe return type of the debounced function to void, documenting that thedebounced function does not return the original function's return value orconsider a promisified version if return values are needed.
