do...while loop running not in sequence

I have this loop

var loginName = 'Ben';
var loginCode = 'abc';
var loginCheck = true;
function loginAccess() {
  do {
    var loginAttempt = prompt("What is your name");
    if (loginAttempt !== loginName) {
      alert("Sorry, that's not it");
    } else {
      break
    }
  } while (loginCheck);
}
 do {
    var loginAttempt = prompt("What is your code");
    if (loginAttempt !== loginCode) {
    alert("Sorry, that's not it");
  } else {
    break
  }
} while (loginCheck);

loginAccess();

Why is it that the code is being asked first instead of asking for the name? I'm wanting the alert dialog box to prompt for the user's name first.

Your first loop is within the loginAccess function, your second one is not. Any code within a function won't be run until the function is called, and since the function is called last in your code the loop within it is the last to run.

If you move the second loop within the function like this:

var loginName = 'Ben';
var loginCode = 'abc';
var loginCheck = true;
function loginAccess() {
  do {
    var loginAttempt = prompt("What is your name");
    if (loginAttempt !== loginName) {
      alert("Sorry, that's not it");
    } else {
      break
    }
  } while (loginCheck);

  do {
    var loginAttempt = prompt("What is your code");
    if (loginAttempt !== loginCode) {
      alert("Sorry, that's not it");
    } else {
      break
    }
  } while (loginCheck);
}

loginAccess();

Then you will end up with the desired result.
