Поможете переписать на fetch или async await?

$.get('#', function(html) {

    var formData = new FormData();
    formData.append('out', 'json');
    formData.append('content', html);

    $.ajax({
        url: "//html5.validator.nu/",
        processData: false,
        contentType: false,        
        data: formData,
        dataType: "json",
        type: "POST",
        success: function(res) {
            console.log(res);
        },
        error: function(error) {
           console.warn(error');
        }
    });
});
