<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")
</head>
<body>
    <div class="navbar navbar-inverse navbar-fixed-top">
        <div class="container">
            <div class="navbar-header">

                </ul>
                @Html.Partial("_LoginPartial")
            </div>
        </div>
    </div>
    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            @RenderSection("scriptSection", required: false)
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>


2)- Index.cshtml -

@{
    ViewBag.Title = "Home Page";
}

@section scriptSection{
    <script type="text/javascript">alert('hello index page');</script>
}

<div class="jumbotron">

    </div>
</div>

3)- Contactus.cshtml

@{
    ViewBag.Title = "Contact";
}
<h2>@ViewBag.Title.</h2>
<h3>@ViewBag.Message</h3>

@section scriptSection{
    <script type="text/javascript">alert('hello contactus page');</script>
}
<address>
    One Microsoft Way<br />
    Redmond, WA 98052-6399<br />
    <abbr title="Phone">P:</abbr>
    425.555.0100
</address>

<address>
    <strong>Support:</strong>   <a href="mailto:Support@example.com">Support@example.com</a><br />
    <strong>Marketing:</strong> <a href="mailto:Marketing@example.com">Marketing@example.com</a>
</address>

4) AboutUs.cshtml

in this page not create scriptSection

Once the running application, script which are witten under scriptSection on Index page will be fired.
Now click on About link script will not get executed because in AboutUs.cshtml we do not create scriptSection and if click on Contact link, script section will be executed.

Note: 
 @RenderSection("scriptSection", required: true)
 if set to required true then in every view like Index/About and ContactUs.cshtml pages we have to create scriptSection{} otherwise when click on About link then it will be throw error and for others link home and Contact it will be worked fine because on both views we have created script section{}.
