[JavaScript] Title Case a Sentence

JavaScript
1

Hi,

I’m attempting to solve this problem. I came up with the following solution

function titleCase(str) {
  let strArr = str.split(" "), finStr = [];
  for(let i = 0; i < strArr.length; i++) {
    for(let j = 0; j < strArr[i].length; j++) {
      if (j === 0) {
        finStr.push(strArr[i][j].toUpperCase());
      } else {
        finStr.push(strArr[i][j].toLowerCase());
      }
    }
    finStr.push(" ");
  }
  return finStr.join("");
}

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

It returns what I need, but it fails to solve all the test cases from freeCodeCamp.

What do the failing tests say?

I get these messages

// running tests
titleCase("I'm a little tea pot") should return I'm A Little Tea Pot.
titleCase("sHoRt AnD sToUt") should return Short And Stout.
titleCase("HERE IS MY HANDLE HERE IS MY SPOUT") should return Here Is My Handle Here Is My Spout.
// tests completed
// console output

You are adding an extra space to the end of all of your strings.

I see now. Thanks for your help!
One more question… Does my code make sense? How can I improve it?

If you haven’t already made this change to your code, I suggest removing the finStr.push(" ") entirely and changing your finStr.join("") to finStr.join(" ") this will add spaces between your words only.

I used the trim method, but your version makes much more sense.

I’m glad I could help. Happy coding!
