Title Case a Sentence: Expected matches Actual

Tell us what’s happening:
The output looks correct, I know the solution is not optimal however I’m wondering why the tests are not passing?
Because what’s showing in the console does indeed match the expected outcome.


Your code so far

function titleCase(str) {
  var toLower = str.toLowerCase().split(' ');
  var newStr = '';
  for (var i = 0; i < toLower.length; i++){
newStr += toLower[i].replace(toLower[i].charAt(0),  toLower[i].charAt(0).toUpperCase());
    newStr += ' ';
  return newStr;

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

Link to the challenge:

It’s failing because of this:

newStr += ’ ’

You’re adding a space after every single word, including the last word. You can’t see it, but it’s there after the last word, which means instead of returning “I’m A Little Teapot” you’re actually returning "I’m A Little Teapot ".
