In nodejs, when working with a database, does all logic need to be stored within a callback?

Question

Node.js

For example, we get from mysql which field

connection.connect();
   
  connection.query('SELECT * from `etc`', function(err, rows, fields) {
    if (err) throw err;
    console.log('Телефон: ', rows[0].phone);
  });

  connection.end();

it turns out that all manipulations with the received data must be done within the second argument of the connection.query method?

yes, it's asynchronous vermicelli and the benefits of non-blocking code. If you don’t like this option, everything that needs to be processed in callbacks should be wrapped in promises and use async await constructs
