Print range using for-loop JavaScript

I need to print a range of numbers in a range using a function and a for-loop. Again I'm stuck on the return value. I believe my code is sufficient for the task but if you have a better idea I'm all ears.

function printRange(rangeStart, rangeStop) {    
    var text = "";
        for (var i = rangeStart; i < rangeStop; i++) {
            text += i + ',';
        }
    return text;
    var result = text;
}

printRange(20, 47);

The 'result' is ought to print the numbers 20,21,22...,46,47 but of course it doesn't... Any help is appreciated. Regards, Thomas

function printAllNum(rangeStart, rangeEnd){
  for(let i = rangeStart; i <= rangeEnd; i++) {
  document.write(i + " ")}
}
printAllNum(1,20);

There are two things you need to fix - your code doesn't print rangeStop, but it does include a trailing comma.

You can fix the former by changing your loop end condition to use <=, and String.prototype.slice can do the latter.

function printRange(rangeStart, rangeStop) {
  var text = "";
  for (var i = rangeStart; i <= rangeStop; i++) {
    text += i + ',';
  }

  return text.slice(0, -1);
}

document.write(printRange(20, 47));
