Title Case a Sentence bug(?)

JavaScript
1

Tell us what’s happening:
I know this code is not the best one because I did not use string methods before JS. The code passes for every conditions but not the “sHoRt AnD sToUt”. Although this does not pass, it works! I even split it to an array to see if there is a whitespace but there is not. Again I know this is not the best code and I can use more eligible codes but I want to know why it does not pass. Thanks.

Your code so far

var upperCase = [];
var slice = [];
var lowerCase = [];
var processedStringArray = [];
var processedString;
var finalProcess;
function titleCase(str) {
  var arrayOfStrings = str.split(/\s+/g);
  for(var i = 0; i < arrayOfStrings.length; i++) {
    upperCase[i] = arrayOfStrings[i].charAt(0).toUpperCase();
    slice[i] = arrayOfStrings[i].slice(1);
    lowerCase[i] = slice[i].toLowerCase();
    processedStringArray[i] = upperCase[i] + lowerCase[i]; 
    processedString = processedStringArray.toString();
    finalProcess = processedString.replace(/,/g , " ");
  }
  return finalProcess;
}

titleCase("sHoRt AnD sToUt");

The problem is that you’re using global variables. If you move all of your variables to be inside of your function, it works. Make this a habit that you follow because global variables will introduce a lot of bugs into your code.
