# Repeat a string repeat a string - part duex

So I got one solution (attempt # 1) but now I’m trying to make it cleaner (attempt # 2).

I see that the code solution says to use REPEAT method. But I went down the += operator and now I want to see why it won’t work. I think the looping is adding a lot more repeats than I want but I can’t tell why. Can someone please review my attempt # 2 code? Thank you.

``````// Attempt # 1
function repeatStringNumTimes(str, num) {
// repeat after me
strungtogether = str;
if (num < 0) {
strungtogether = "";
}else
for (i = 0; i < num-1; i++){
strungtogether += str;
}

return strungtogether;
//   console.log(strungtogether);
}

repeatStringNumTimes("abc", 3);

// Attempt # 2
function repeatStringNumTimes(str, num) {
// repeat after me
if (num < 0) {
str = "";
console.log(str);
}else
for (i = 0; i < num-1; i++){
str += str;
console.log(str);
}
//   console.log(strungtogether);
}

repeatStringNumTimes("abc", 3);
``````

Note that your attempt #1 still fails where the second parameter is 0.

As for attempt #2, there are a number of problems, the most serious being that your function lacks a `return` statement.

As for why it’s repeating the string too many times, consider this similar analogy:

``````function addStuff(val, reps) {
for (let i = 0; i < reps; i++) {
val += val;
}
return val;
}
