Title Case a Sentence - not sure why solution isn't valid

[cyyc1498]

I wrote this code and the output seems to be right when I console.log it but it is not accepting it as an answer. Would anyone be able to explain why?

   **Your code so far**

function titleCase(str) {

str = str.toLowerCase().split(" ")
 var empt = "";
 
 for(var i=0;i<str.length;i++){
   var cap = str[i][0].toUpperCase();
   empt += str[i].replace(str[i][0],cap)+" ";
 } 
 
 return empt;
 
}


console.log(titleCase("I'm a little tea pot"));

Hi @cyyc1498 !

Welcome to the forum!

You have extra space at the ends of your string.

You need to get rid of it.

If you google, “how to get rid of space at ends of string javascript”
then it will tell you the string method you can add at the end here

@cyyc1498

return empt;
