Fast Autocomplete Plugin For Bootstrap 4 - typeahead.js

This is the upgraded and jQuery version of Twitter's typeahead.js library which provides a fast, performant auto-complete functionality for Bootstrap 4 based web app.

How to use it:

1. Load the main JavaScript file bootstrap-typeahead.js after jQuery & Bootstrap's JS files.

<script src="/path/to/jquery.slim.min.js"></script>
<script src="/path/to/bootstrap.min.js"></script>
<script src="js/bootstrap-typeahead.js"></script>

2. Attach the plugin to the input field and specify the dataset as follows:

<input type="text" class="form-control" id="field-state" placeholder="State">

document.addEventListener('DOMContentLoaded', function(){
  var substringMatcher = function(strs) {
      return function findMatches(q, cb) {
          var matches, substringRegex;
          matches = [];

          substrRegex = new RegExp(q, 'i');

          $.each(strs, function(i, str) {
              if (substrRegex.test(str))
                  matches.push(str);
          })

          cb(matches);
      }
  }

  var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
        'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',
        'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana',

  $('#field-state').typeahead(
    {

    },
    {
