I would like to remove the jquery from here and do it with simple javascript. How can I do that? Or how could I do that but in a simpler and better way?

<script>
        let serverData = {
            'server1': [],
            'server2': [],
            'server3': [],
        };
        const body = $('body');
        function displayInTable(server) {
            
            if(serverData[server]) {
                
                const serverTable = $(`tbody#${server}`);
                
                serverTable.html('');
                serverData[server].forEach((user) => {
                    
                    serverTable.append('<tr><td>'+user.id+'</td><td>'+user.nume+'</td><td>'+user.autor+'</td><td>'+user.album+'</td><td>'+user.gen+'</td><td>'+user.an+'</td></tr>');
                })
            }
        }


        async function firstFetch() {
            
            const request = await fetch('ajax/colectareDate.php');
            const response = await request.json();
            if(response) {
              
                Object.keys(response).forEach((server) => {
                    
                    serverData[server] = response[server]
                    displayInTable(server)
                })
            }
        }
[13:35]

        body.on('submit', '#mainForm', async function(e) {
            e.preventDefault(); 

            
            const request = await fetch('ajax/inserareDate.php?'+$(this).serialize());
            const server = 'server1';
           
            serverData[server] = await request.json();
            
            displayInTable(server);
        });
        
        body.on('click', '.syncButton', async function() {
            
            const from = $(this).attr('data-from');
            const to = $(this).attr('data-to');
          
            const request = await fetch('ajax/sincronizare.php?from='+from+'&to='+to);
            
            serverData[to] = await request.json();
            
            displayInTable(to);

        });
