Scheduling Updates

Instructions for batching updates across independent regions with predictable timing.

When to Use

Use this when a UI has multiple regions that should update independently or when updates are expensive.

Steps

1. Assign each UI region its own Handle.
2. Use batch() to coalesce update scheduling in the same tick.
3. Create a scheduler that batches updates with queueMicrotask.
4. Use startTransition() for non-urgent work to keep the UI responsive.
5. Deduplicate updates per region within a single flush.
