How re-render works?

Hey! This is more of a question rather than a bug/suggestion.

If I change a single item of the entire table, and then run a `setTableData(data)`, will it re-render the entire table or just the parts that have actually changed?

Is there some kind of key property or key verification during the render process? Or should I specify something like a keyExtractor manually?

For some context: I am developing an application that uses websocket and setting the table to re-render every time data arrives from the server.

Thank you so much for this amazing library!
