I know this is a lot of work but since the course hasn't talked about .join and .sperate, am I supposed to solve this challenge like this?

Tell us what’s happening:
Describe your issue in detail here.

  **Your code so far**

function titleCase(str) {
const regex = /(?<=\s?)\w+\'\w+|(?<=\s?)\w+/ig;
let wordArray = str.match(regex);
let finalArray = [];
let finalStr = "";
for (let i = 0; i < wordArray.length; i++) {
  let testArray = "";
   testArray = wordArray[i][0].toUpperCase() + wordArray[i].slice(1).toLowerCase();
for (let j = 0; j < finalArray.length; j++) {
  finalStr += finalArray[j] + " ";
let noSpaceStr = finalStr.replace(/((\w+)\s)$/, '$2');
return noSpaceStr;

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

Challenge: Title Case a Sentence

First, congrats on getting a working solution without using some very convenient array methods. Yes, it was more work, but I bet you have a good understanding of how this algorithm works :slight_smile:

But ya, in the “real world” you would definitely use array methods like join to make this much more readable. For example, you can replace everything after the first for loop with one return statement using join. And using join is not a requirement here. You can use replace with a proper regexp to really shorten the code down to almost nothing.

Now that you have a working solution I don’t see any harm in taking a look at the alternative solutions provided in the hints to get an idea of other ways to solve this challenge. Or, before you do that, try to challenge yourself by rewriting this using a functional approach and only a single return statement.

Note, it’s a bit easier if you put your question inside of your post instead of in the title
