Prompt Title: Update check value state.

The issue with the code is that it is sending the value of the check variable as a property named check in the data payload of the POST request to the backend API. However, the value of check is not being updated to true anywhere in the code snippet provided. Therefore, even if setCheck(false) is called after the response is received, it does not change the fact that the value of check is always false in the payload of the POST request.

To fix this issue, you should update the value of check to true before sending the POST request. You can do this by calling setCheck(true) before calling axios.post(). Here is the updated code snippet:

typescriptCopy code
const [check, setCheck] = useState(false)

// code....

onSubmit={(e) => {
  e.preventDefault()
  setCheck(true)
  axios.post("http://localhost:8000", {
    check                   
  })
  .then((res) => {
    console.log(res.data)
    setCheck(false)
  })

// code...

<button type="submit" value="submit" name="submit">submit</button>

Now, when the form is submitted, setCheck(true) is called before the POST request is sent, which updates the value of check to true. Then, when the response is received, setCheck(false) is called, which sets the value of check back to false, so that the user can submit the form again if needed.
