Identify the reasons why this code will not work correctly:
(Several correct answers)

<form method="post" action="/app/send" name="myForm">
   ...
   <input type="submit">
</form>

var form = document.querySelector('#myForm');

form.addEventListener('onsubmit', onSubmit);

function onSubmit() {
  // do check #myForm fields...
}

Accepted Answer

Upon validation, the browser may reload the page without letting the JavaScript execution finish.

Accepted Answer

The `onsubmit` event does not exist.

Accepted Answer

The selector to target the tag is incorrect.

Answer

The 3rd parameter of the `addEventListener` method is missing, the boolean indicating the capture phase of the event.

Answer

The `onSubmit` function is declared after the event, which will cause an error:` ReferenceError: onSubmit is not defined`
