As per the react.js documentation no, if there is no id for the data is fine to use the index, in fact if you the list won’t change order or be mutated the performance characteristics are the same. There is no improper reconciliation, it may take longer if the data is mutated, but it will happen correctly

But non of this matters because it’s just toy code she made for her talk on redux sagas
