  str="";
  for (i=0; i<arryStr.length;i++){
    var temp =arryStr[i].charAt().toUpperCase();
    var lower="";
     for(j=1;j<arryStr[i].length; j++){
       lower+=arryStr[i].charAt(j).toLowerCase();

     }
    str+=temp+lower+" ";

  return str;
}

I think the line str+=temp+lower+" "; add a whitespace to the end of the text when in the last iteration which makes the strings not match. Hint: Have a look at Array.prototype.join() to avoid the problem.

@cjoshmartin as @pnahratow suggests, double check the spaces you add when you join strings. If you get stuck or have questions with a challenge in the future, please first ask questions to the Help Room. Happy coding!
