Now we will also define the javascript code which will be required for animating the text like typewriter effect

 <script type="text/javascript" src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
    <script>
(function ($) {
    "use strict";
    var pluginName = "textplayer";
    var contentClassName = ".textPlayerContent";

    $.fn.textplayer = function (option) {
        if(this.length > 1){
            this.each(function () {$(this).textplayer(option);});
            return this;
        }

        var instance = this;
        var $this = $(this);

First of all we are also including the jquery cdn library and also we are also including the javascript code for animating the text. Now we need to define the html for animating the text

<div class="container">
        <h1>jQuery textPlayer: Video Player Like Text Typing Example</h1>
        <h3>Total 11 slides are there and for each slide the duration is set to 5 seconds</h3>
        <div id="textPlayerContainer" style="border: 1px solid #e4e4e4">
            <pre class="textPlayerContent"></pre>
        </div>
    </div>

<h1>jQuery textPlayer: Video Player Like Text Typing Example</h1>

<h3>Total 11 slides are there and for each slide the duration is set to 5 seconds</h3>

</div>

As you can see we have a video player in which we will be animating the text. Now we will be writing the javascript code which will be animating text as shown below

As you can see we have defined the programming text and stored it inside in different variables. And lastly we are playing the text animation like typewriter effect inside the video. For this we are using the start() method to start the animation. Also we are setting the video player height and width and also we are including all the texts inside the texts array.
