I would like to know if this code follows recommended practices and standards for AJAX/PHP calls.

ajax.js:

function getTableData() 
 const xmlhttp = new XMLHttpRequest();
 xmlhttp.onreadystatechange = function() 
 if (this.readyState === 4 && this.status === 200) 
 document.querySelector('#test-table tbody').innerHTML = this.responseText;
 
 
 xmlhttp.open('GET', 'ajax.php', true);
 xmlhttp.send();


$(document).ready(function () 
 getTableData();
);

ajax.php:

<?php
$data = prepareDataForTable();
$data_length = count($data);
$columns = 4;

for ($row = 0; $row < $data_length; $row += $columns) 
 echo '<tr>';
 for ($col = 0; $col < $columns && ($col + $row) < $data_length; $col++) 
 echo '<td>' . $data[$col + $row] . '</td>';
 
 echo '</tr>';

?>

ajax.html:

<table id="test-table">
 <tbody>
 </tbody>
</table>

I specifically want to know if this is a good way to send information back to the client - by running loops and echoing output.
