Repeat a String - Am I doing something wrong?

[nix]

Hi!

I solved the exercise from " Basic Algorithm Scripting: Repeat a String Repeat a String". This is my code:

function repeatStringNumTimes(str, num) {
  fstr = ""
  for (let i = 0; i < num; i++){
    fstr += str
  }
  return fstr;
}

repeatStringNumTimes("abc", 3);

The problem is that the program doesn’t accept my answer. I would like to know if I am making a mistake.

@nix

fstr = ""

You need to declare this.

@nix You have to declare fstr using let or var Happy Coding!
