🛠️ Refactor suggestion

Add input validation for the size parameter.

The chunk implementation is correct, but it lacks validation for the size parameter. Consider adding validation to handle edge cases where size is less than or equal to 0, which could cause infinite loops or unexpected behavior.

 export function chunk<T>(array: T[], size: number): T[][] {
+  if (size <= 0) {
+    throw new Error('Chunk size must be greater than 0');
+  }
   const chunks: T[][] = [];
   for (let i = 0; i < array.length; i += size) {
     chunks.push(array.slice(i, i + size));
   }
   return chunks;
 }

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
less than or equal to 0. Add input validation at the start of the function to
check if size is a positive integer greater than 0, and throw an error or return
an empty array if the validation fails to prevent invalid usage.
