This is your code, with added console.log statements, check those to figure out what’s wrong.

function titleCase(str) {
  console.log(str.length) // 20
  let words, capitalizeSentence = '';
  words = str.toLowerCase().split(' ')
  for (let i = 0; i < words.length; i++) {
    capitalizeSentence += words[i][0].toUpperCase()
    capitalizeSentence += words[i].slice(1)
    capitalizeSentence += ' '
  }
  console.log(capitalizeSentence.length) // 21
  return capitalizeSentence;
}

titleCase("I'm a little tea pot");
//titleCase("HERE IS MY HANDLE HERE IS MY SPOUT")
//titleCase("sHoRt AnD sToUt")

     let z = 0;
       for(var i = 0; i < arr.length ; i++){
            if(arr[i] == " "){
                 z = 0;
            }
            else { if(z == 0){
                 arr[i] = arr[i].toUpperCase();
                 z = 1
            }else{
                  arr[i] = arr[i].toLowerCase();
                 }
            }
        }

I was wondering if there is a way to refer to the character which comes after the white space. Can you use (\s + 1)?
