JSON.parse overrides the original values which result into unexpected behavior

I am taking values from local storage, But when I am doing filtering it is affecting the original values in the storage.

How can I overcome this problem?

  const localData = JSON.parse(localStorage.getItem("icon"))[`${page}`];

  useEffect(() => {
    let tempData = localData?.filter((item) => item.iconTitle === iconName);
    setData(tempData);
  }, [iconName, page]);

 useEffect(() => {
    const getData = localStorage.getItem("icon");
    const localData = JSON.parse(getData)[`${page}`];
    console.log(localData);
    let tempData = localData?.filter((item) => item.iconTitle === iconName);
    setData(tempData);
  }, [iconName, page]);

  console.log(data);
  const renderTooltip = () => (
    <Tooltip style={{ backgroundColor: "white" }}>
      {(iconName && data[0]?.description) || `No Data Available`}
    </Tooltip>
  );
