You can modify your existing function to accept an array of words, and process the words one by one:

function typeIt(words) {
  var letterIndex = 0;
  var wordIndex= 0;
  var h1 = $("#myTypingText");

  var SI = setInterval(function() {
    if (letterIndex === words[wordIndex].length) { // if at end of current word
      wordIndex = (wordIndex + 1) % words.length;  // go to next word
      letterIndex = 0;                             
      h1.empty();                                  // clear output div
  }, 70);

typeIt(["beautiful", "awesome", "nice", "wonderful"]);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="myTypingText"></div>

Note that you don't need to .split("") the word, because you can directly reference the individual characters in a string with the same square-bracket syntax as referencing array elements, e.g., "text"[2] is "x".
