Removing backslash out of my string

I am doing the Title Case a String challenge, and my final code is outputting (I can’t get the backslash to show, but it’s in the word “I’m) ‘I’m a little tea pot’, which won’t pass the test due to the slash. I’ve tried googling how to remove it. I’m getting things like adding “.replace(”\/g”, “”)", but for one, I dont really understand the syntax, and also it’s not working. Any help is appreciated.

function titleCase(str) {
  let words = str.split(" ");
  for (var i=0; i<words.length; i++){
    words[i][0].toUpperCase();
  };
  let finished = words.join(" ");
  return finished;
}

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


I assume you are using Node to test your code? That \' is not what is causing your code to fail. That ’ signifies there is a literal single quotation mark there. The reason your code fails, is that your function returns ‘I\’m a little tea pot’ instead of ‘I\’m A Little Tea Pot’

Oh man, I feel like an idiot haha. Back to the drawing board, thanks.
