advanced patterns with async/await in a recursive function in Node.js causing stack overflow

I'm running into an scenario with a recursive function in Node.js that uses async/await. The function is designed to process items from a database in batches, but I keep getting a stack overflow behavior when the number of items exceeds a certain limit. Here's a simplified version of what I'm trying to achieve: ```javascript const processBatch = async (items) => { for (const item of items) { await processItem(item); } }; const recursiveProcessing = async (offset = 0, limit = 100) => { const items = await fetchItemsFromDatabase(offset, limit); if (items.length === 0) return; await processBatch(items); await recursiveProcessing(offset + limit, limit); }; recursiveProcessing(); ``` The `fetchItemsFromDatabase` function retrieves items based on the `offset` and `limit` parameters. However, when I call `recursiveProcessing`, it starts to throw a `RangeError: Maximum call stack size exceeded` after a few iterations. I've tried increasing the stack size with `node --stack-size=10000`, but that didn't help. I also considered that the recursion depth might be too high, so I switched to an iterative approach, but it didn't resolve the scenario either. Is there a better way to handle this without running into a stack overflow? Should I be using a different structure to process these items incrementally? If anyone has faced a similar scenario, I would appreciate your insights!
