twitter.typeahead.js doesn't work in asp.net core mvc project – Twitter bootstrap

I am working on a asp.net mvc project which will show the related search results ahead typing below the search box. I’ve added the twitter.typeahead.js with bower package manager in the project. Here is my code 

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>  
    <script src="~/lib/typeahead.js/dist/typeahead.bundle.js"></script>
    <title></title>
</head>
<body>
    <div id="bloodhound">
        <input class="typeahead" type="text" placeholder="States of USA">
    </div>

</body>
</html>

<script type="text/javascript">

    $(document).ready(function () {
        var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
            'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',
            'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana',
            'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota',
            'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire',
            'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota',
            'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island',
            'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont',
            'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'
        ];

        var states = new Bloodhound({
            datumTokenizer: Bloodhound.tokenizers.whitespace,
            queryTokenizer: Bloodhound.tokenizers.whitespace,
            // `states` is an array of state names defined in "The Basics"
            local: states
        });

        $('#bloodhound .typeahead').typeahead({
            hint: true,
            highlight: true,
            minLength: 1
        },
            {
                name: 'states',
                source: states
            });
    });
</script>

Now it’s giving this error

Use of getPreventDefault() is deprecated.Use defaultPrevented instead.

    Lets get this working 😛

    DEMO: https://jsfiddle.net/ipsjolly/6ydvth9q/1/

    TypeAhead version 1.1.1
    URL: https://cdnjs.cloudflare.com/ajax/libs/corejs-typeahead/1.1.1/typeahead.jquery.min.js

    jQuery is latest

    Source: http://twitter.github.io/typeahead.js/examples/

    TypeScript code is without Bloodhound I dont know why this is for 😀

    HTML

    <div id="the-basics">
  <input class="typeahead" type="text" placeholder="States of USA">
</div>

    JS

    <script type="text/javascript">
    var substringMatcher = function(strs) {
        return function findMatches(q, cb) {
            var matches, substringRegex;

            // an array that will be populated with substring matches
            matches = [];

            // regex used to determine if a string contains the substring `q`
            substrRegex = new RegExp(q, 'i');

            // iterate through the pool of strings and for any string that
            // contains the substring `q`, add it to the `matches` array
            $.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',
        'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota',
        'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire',
        'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota',
        'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island',
        'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont',
        'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'
    ];

    $('#the-basics .typeahead').typeahead({
        hint: true,
        highlight: true,
        minLength: 1
    }, {
        name: 'states',
        source: substringMatcher(states)
    });
</script>

    Just to clarify, Bloodhound is not the issue.

    Bloodhoud is the typeahead.js suggestion engine

    There is a jsfiddle added on this stack overflow answer, that works perfectly with bloodhound.

    I have also created one jsfiddle with the updated version typhead bloodhound and jquery version

    Jquery: 3.2.1
    Typehead: 1.1.1

    You could try this version for your project

    const suggestions = [{
    value: 'bloodhound1'
}, {
    value: 'bloodhound2'
}, {
    value: 'bloodhound3'
}, {
    value: 'typeahead1'
}, {
    value: 'typeahead2'
}]

var bloodhoundSuggestions = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    sufficient: 3,
    local: suggestions
});

const $tagsInput = $('#tagsInput')
$tagsInput.typeahead({
    hint: true,
    highlight: true,
    minLength: 1
}, {
    name: 'suggestions',
    displayKey: 'value',
    source: bloodhoundSuggestions
});
