How to make a synchronous loop in Node.JS?

Question

JavaScript

Hello. I'm learning to program a little.
I have a number of links and I want the script to download the contents of each in turn and write it to the database. On php it worked with a simple cycle, it doesn't work here. I did so. But it is interesting to learn from experienced developers how you would do it.

var adresses = []; // ten values
connection.connect(); // mysql connection

function get(address, callback) {
  http.get(address, function(res) {
    var getted;
    res.on('data', function(part) {
      getted += part.toString();
    }).on('end', function() {
      callback(getted);
    });
  });
}

function getPages(counter) {
  get(adresses[counter], function(res) {
    connection.query('INSERT INTO porn (id, link) VALUES ('+(counter+1)+', '+res+')', function(error, result) {
      if (counter < adresses.length) {
        getPages(counter+1); // continue
      } else {
        connection.end(); // mysql close
      }
    });
  });
}

getPages(0);

Below is the code that I wrote specifically for the example. Something about the same works in my script.

At the heart of Node.js is event-driven and asynchronous (or reactive) programming with non-blocking I/O .
