Playing with the begginer JavaScript loops - how do I print all new sets of 8 numbers on a new line?

Im trying to make the random number generator to a lotto number generator code. I put the generator into a function with numbers 1-45 8 times. then I created another function that calls the generator x times, and it is working fine only that all results are printed to 1 long sequence of numbers. How do I add a new line after each set of 8 numbers? Also is there a better way to call the function x times?

function randomNumber(upper) {
  return Math.floor( Math.random() * upper ) + 1;
}
function lotto(){
var counter = 0;
while (counter < 8) {
  var ranNum =  randomNumber(45);
  document.write(ranNum + ' ,' );
  counter += 1;
}
}

var CallLotto = 0;
for(i =0; CallLotto<5; i++) {
  CallLotto += 1;

  lotto();
}

You could add a HTML line break as below:

document.write(ranNum + ',<br/>' );

I'm really new at javascript but I gave it a shot and this is what I came up with.

var html = '';
var lotoNumbers;

function randomNumber(upper) {
  return Math.floor( Math.random() * upper ) + 1;
}

function number () {
  var nums = '(';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ', ';
  nums += randomNumber(45) + ')';
  return nums;
}

function print(message) {
  document.write(message);
}

for (var i = 0; i < 8; i += 1) {
  var lotoNumbers = number();
  html += 'Your lucky loto numbers are ' + lotoNumbers + '<br/>';
}

print(html);

Good idea , so I have the first part working but instead of just calling the function 5 times after each function call load the results in a variable..I'll try when I get home...thank you
