You handle cell edits. You handle range fills. You handle copy and paste. Too many event handlers make code messy.

Use a JavaScript Proxy. Wrap your data source. The grid reads data through the get trap. The grid writes data through the set trap.

The grid sees a normal object. You control the logic. Your data lives in a Map or a database. The proxy routes the request.

You stop using events for every data change. The row object is an adapter. Centralize your sync logic in one place.

Follow these rules:

• Do not create proxies in render loops.
• Keep proxy identity stable.
• Watch performance with large datasets.

The component does not need to own the data flow. Give it a simple object. Make the object smart.
