Title Case a Sentence with join() not accepted

[sheila.markazi]

Tell us what’s happening:

It looks to me that the code I’ve written yields the correct answer. But freeCodeCamp is marking it as incorrect. Am I not seeing something? Could someone point out what requirement I’ve missed? I don’t think I have extra spaces at the beginning or end of my output, so I don’t think it’s that. I know there are similar topics already posted, but I didn’t see one that used join(), so I went ahead and made this post.

  **Your code so far**

function titleCase(str) {
let lower= str.toLowerCase();
let newArr=[];

let splitStr = lower.split(" ");

for (let i=0; i<splitStr.length; i++){
  newArr[i] = splitStr[i][0].toUpperCase();
  for (let j = 1; j<splitStr[i].length; j++){
    newArr[i]+=splitStr[i][j];   
  }
}

let newStr = newArr.join(' ');
console.log(newStr);
return str;
}

titleCase("sHoRt AnD sToUt");
