Challenge Title Case a Sentence has an issue.

Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:

var test = [];
var myArray = [];
function titleCase(str) {
  myArray = str.toLowerCase().split(' ');
  for (i = 0; i < myArray.length; i++) {
   test.push(myArray[i][0].toUpperCase() + myArray[i].substr(1)); 

  }
  return test.join(" ");

}

titleCase("sHoRt AnD sToUt");

Global variables are bad news. Think about what happens if you run that function more than once. Thanks and happy coding!
