Capitalize the first letter of every word:

let capitalizeFirstLetter = function (sentence) {
  let wordArray = sentence.toLowerCase().split(" ");
  let newSentence = [];
  
  for (let word of wordArray) {
      let capWord = word[0].toUpperCase() + word.substring(1);
      newSentence.push(capWord);
  }
  return newSentence.join(" ");
}

function titleCase(str) {
   var splitStr = str.toLowerCase().split(' ');
   for (var i = 0; i < splitStr.length; i++) {
       // You do not need to check if i is larger than splitStr length, as your for does that for you
       // Assign it back to the array
       splitStr[i] = splitStr[i].charAt(0).toUpperCase() + splitStr[i].substring(1);     
   }
   // Directly return the joined string
   return splitStr.join(' '); 
}

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