Как отправить AJAX запрос к API

const $form = document.getElementById(`myForm`);

$form.addEventListener(`submit`, e => {
    e.preventDefault();
    fetch($form.action, {
        method: $form.method,
        body  : new FormData($form)
    })
        .then(response => response.text())
        .then(data => console.log(data))
        .catch(err => console.error(err));
});

        <span class="close">&times;</span>
