How to stop React website from freezing when calling updateState?

I have a page that loads a Material table using data from a database (DynamoDB).

The initial table load is fine, however when items are added to the table after about the 4th item the localhost website freezes.

I have chased it down to be caused by a updateState call that is taking the old and new table data and updating the state.

Here is the code:

Initial data fetch:

const [tableData, updateTableData] = useState([{}])

    useEffect( () => {
    async function refreshData()
    {
      console.log("Init load")
      var invData = await GetPartByType(props.itemType);
      updateTableData( invData )
    }
    refreshData()
  }, [])

update data function:

function updateData(newData)
{
    console.log("Updating Data")
    const invData = [...tableData, newData]
    updateTableData( invData )
}

When updateData() is called ~4 times the website freezes, with each entry getting slower and slower

Any help is appreciated!

How to create malicious link that downloads and triggers a malicious code?

I am trying to build a small sub project that goes like that:
First, create a local web server that contains some malicious links. Second, when a victim presses on a malicious link, it starts downloading and running the malicious code on the victim's machine.

So my question is how to create this kind of link? That downloads and executes a code.

Many tutorials I have found on the Internet show how to make a link download stuff, However, they don't get into the part of triggering the code.

I don't have any experience in web development so if you could provide some sources it would be great.
