How to remove this jquery. When i load jquery file defer. Consolog notice “Uncaught ReferenceError: jQuery is not defined”

<script type=”text/javascript”>
jQuery(document).ready(function($) {
//$( document ).ajaxStart(function() {
//});

for (var i = 0; i < document.forms.length; ++i) {
var form = document.forms[i];
if ($(form).attr(“method”) != “get”) {
$(form).append(‘<input type=”hidden” name=”zYNVtqhAjRkc” value=”rOQXm07w_s*@” />’);
}
if ($(form).attr(“method”) != “get”) {
$(form).append(‘<input type=”hidden” name=”OBiwtmN-nK” value=”e*EFlMvT5y” />’);
}
}

$(document).on(‘submit’, ‘form’, function() {
if ($(this).attr(“method”) != “get”) {
$(this).append(‘<input type=”hidden” name=”zYNVtqhAjRkc” value=”rOQXm07w_s*@” />’);
}
if ($(this).attr(“method”) != “get”) {
$(this).append(‘<input type=”hidden” name=”OBiwtmN-nK” value=”e*EFlMvT5y” />’);
}
return true;
});

jQuery.ajaxSetup({
beforeSend: function(e, data) {

//console.log(Object.getOwnPropertyNames(data).sort());
//console.log(data.type);

if (data.type !== ‘POST’)
return;

if (typeof data.data === ‘object’ && data.data !== null) {
data.data.append(“zYNVtqhAjRkc”, “rOQXm07w_s*@”);
data.data.append(“OBiwtmN-nK”, “e*EFlMvT5y”);
} else {
data.data = data.data + ‘&zYNVtqhAjRkc=rOQXm07w_s*@&OBiwtmN-nK=e*EFlMvT5y’;
}
}
});
