take a string, change the first character of each word into capitalized letter :)

titleCase.js

function titleCase(str) {
  var strLowerCase = str.toLowerCase();
  var split = strLowerCase.split(" ");
    for (var i = 0; i< split.length; i++) {
      var firstChar = split[i].charAt(0).toUpperCase(); 
      split[i] = firstChar + split[i].substr(1);
    }
  var newStr = split.join(" ");
  return newStr;
}

titleCase("fOrce aWAKENS");
