How to return a specific range of indexes from within in a JSON Array?

I have this array of objects that I retrieved from an API. It is continuously being updated everyday. The array consists of a timeseries of cases for everyday. I want to use this array to return the cases for each date for the last week. I have fetched the country name and filtered the array, so it only shows the user's country's array. I was thinking I can map across the dates of the array to find the last 7 indexes. Is there a way to do this?

useEffect(() => {    if (mappedLocation !== null) {      axios        .get("https://api.covid19india.org/v4/min/timeseries.min.json")        .then((response) => {          setEarliest2(response.data);          const stateArray = response.data.filter(            (item) => item.country === mappedLocation.stateShort          );
