react-key-prop

Using array index as a key prop in React lists causes component state drift during re-renders because changing indices break element identity reconciliation when items are added, removed, or reordered.

Generate stable, unique IDs once at data load using a deterministic id generator when your data items lack unique IDs, ensuring reliable React list reconciliation and preventing state drift during dynamic updates.

The best way to refactor React list rendering is to replace index-based keys with a stable, data-derived id for each item, ensuring correct element identity during reconciliation when items are added, removed, or reordered.

You need to enforce stable keys for React component lists whenever items may be added, removed, or reordered, as unstable or missing keys cause component state drift and incorrect element identity during reconciliation.

Array index as keys is discouraged for dynamic React lists where items may be added, removed, or reordered, but static lists with unchanging order are less prone to the component state drift caused by unstable element identity.

Yes, React key prop enforcement works without dependencies by requiring data items to supply a stable id or using a deterministic id generator to maintain correct element identity during list reconciliation.
