def chunk_list(lst, n): return [lst[i:i+n] for i in range(0, len(lst), n)]

Output (excerpt)

```python
def chunk_list(lst, n):
    """
    Split a list into consecutive sublists of length ``n``.

    The final sublist may be shorter than ``n`` if ``len(lst)`` is not
    an exact multiple of ``n``. Order is preserved.

    Args:
        lst: Source iterable, materialized into a list-like sequence.
        n: Chunk size. Must be a positive integer.

    Returns:
        A list of lists, where each inner list is a contiguous slice of ``lst``.

    Example:
        >>> chunk_list([1, 2, 3, 4, 5], 2)
        [[1, 2], [3, 4], [5]]
    """
    return [lst[i:i+n] for i in range(0, len(lst), n)]

code

function debounce(fn, ms){let t;return function(...args){clearTimeout(t);t=setTimeout(()=>fn.apply(this,args),ms);};}

Output (excerpt)

```javascript
/**
 * Wrap a function so that calls separated by less than ``ms`` milliseconds
 * collapse into a single trailing call. Useful for limiting work on
 * resize, scroll, or rapid input events.
 *
 * @param {Function} fn - The function to debounce.
 * @param {number} ms - The quiet-period in milliseconds.
 * @returns {Function} A debounced wrapper preserving ``this`` and arguments.
 *
 * @example
 *   window.addEventListener('resize', debounce(layout, 200));

CREATE PROCEDURE ArchiveOldOrders @Days INT AS BEGIN INSERT INTO orders_archive SELECT * FROM orders WHERE created_at < DATEADD(day,-@Days,GETUTCDATE()); DELETE FROM orders WHERE created_at < DATEADD(day,-@Days,GETUTCDATE()); END

Output (excerpt)

```sql
-- ArchiveOldOrders
-- Move rows older than @Days from `orders` into `orders_archive`,
-- then remove them from the live table.
--
-- @Days: Cutoff age in days. Rows where `created_at < UTC_NOW - @Days`
--        are eligible for archive.
--
-- Notes:
--   * Wrap in a transaction in production to avoid partial archive.
--   * Indexes on orders.created_at + orders_archive should exist for
--     this to run in seconds rather than minutes on >1M-row tables.
--   * Use UTC consistently — server local time will drift across DST.
CREATE PROCEDURE ArchiveOldOrders @Days INT AS
BEGIN
  INSERT INTO orders_archive

    WHERE created_at < DATEADD(day, -@Days, GETUTCDATE());
