Struggling with code for "Repeat a string" challenge

Hi guys, I’m really stumped with this one. I’m resisting the temptation to hit up the blog posts and wikis on this challenge because it seems really simple and I should have no problem with it. That said, my code is just returning an empty string and I have no idea why.

Here it is:

function repeatStringNumTimes(str, num) {
  var returnStr = "";
  if (num < 1) {
    return "";
  } else {
    for (i = 0; i < num; i++) {
  return returnStr;

repeatStringNumTimes("abc", 3);

I know that this isn’t caused by the if statement’s empty string because this persists even if I comment-out the if statement. What am I doing wrong here?

you never actually assign anything to returnStr after you have declared it.

returnStr.concat(str); will be ABC in that instance per say.
but when the loop continues returnstr is still empty.
You need to save your concated string somewhere while you loop through it.

Gah I knew it would be something obvious, thanks for the quick response!
