You can write on screen using document.write function

Code:

<html>
<body>
<script>

document.write(' hello');
</script>
</body>
</html>

You can print what is in variable

Code:

<html>
<body>
<script>
var sum=0;
var x=5;
var y=3;
sum=x+y;
document.write(sum);
</script>
</body>
</html>

You can print string :

Code:

<html>
<body>
<script>
var description="x+y= ";
var sum=0;
var x=5;
var y=3;
sum=x+y;
document.write(description+sum);
</script>
</body>
</html>

loop ?
like this

Code:

<html>
<body>
<script>
 
var sum=10;
  for(var i=0;i<sum;i++){
    document.write('Iteration number '+i+'<br/>');
  }

</script>
</body>
</html>
