How to store lines into array after loading a selected local file in javascript

Question

I'm trying to load a text file and store lines within the text file into an array variable. I found a related issue but I want to enhance it furtheremore

<div>
  Select a text file:
  <input type="file" id="fileInput">
</div>
<pre id="displayFile"></pre>


<script>
   var fileInput = document.getElementById('fileInput');
   fileInput.addEventListener('change', function(e) {
          var file = fileInput.files[0];
          var reader = new FileReader();

          reader.onload = function(e) {
              document.getElementById('displayFile').innerText = reader.result;
              myAddress.push(reader.result)
      };
          reader.readAsText(file);
      });
</script>

and I want the lines that are read go into myAddress array

var myAddress = [];

   var fileInput = document.getElementById('fileInput');
   var myAddress = []
   fileInput.addEventListener('change', function(e) {
     var file = fileInput.files[0];
     var reader = new FileReader();
     reader.onload = function(e) {
       document.getElementById('displayFile').innerText = reader.result;
       myAddress = reader.result.split('\r\n')
