Basic Algorithm Scripting:Repeat a String Repeat a String

Basic Algorithm Scripting:Repeat a String Repeat a String


Tell us what’s happening:
What is wrong with this code ? I see in the console, it is returning the required output.

Your code so far

function repeatStringNumTimes(str, num) {
  // repeat after me
  if (num < 0) {
  else {
  var strArr = [];
  for (var i=1; i<=num; i++) {
  return console.log(strArr.join(''));

repeatStringNumTimes("abc", 3);

Your main problem is you are console logging the result instead of returning it.
For exampe this line returns undefined: return console.log(strArr.join(''));

Change all console logs to returns and the code will pass the tests.
Also just as a suggestion, pushing things into an array may not be necessary here because you can simply concatenate strings.

for example like this

let result = "";
for (let i = 0; i < num; i++) {
  result += str;
return result;
