                                    // hey buddy, here are different implementations, choose your favourite !!


// best implementation
repeatStr = (n, s) =&gt; s.repeat(n);


// short
function repeatStr(n, s) {
  return s.repeat(n);
}


// without using repeat
function repeatStr(n, s) {
  var str = &quot;&quot;;
  for (var i = 0; i &lt; n; i++) str += s;
  return str;
}

Thank you! 7
