Strategies for addressing frontend challenges in Bootstrap 4

Currently, I am enrolled in a program to enhance my knowledge of Angular and have encountered a challenge. My project is utilizing the most recent version of bootstrap, which is bootstrap 4. However, I am facing issues with the main page not functioning correctly, displaying output that resembles bootstrap 3.x.

<nav class="navbar navbar-default">
    <div class="container-fluid">
        <div class="navbar-header">
            <a href="#" class="navbar-brand" >Recipe Book</a>
        </div>
        <div class="collapse navbar-collapse">
            <ul class="nav navbar-nav">
                <li><a href="#" >Recipes</a></li>
                <li><a href="#" >Shopping List</a></li>
            </ul>
            <ul class="nav navbar-nav navbar-right">
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle">Manage</a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Save Data</a></li>
                        <li><a href="#">Fetch Data</a></li>
                    </ul>
                </li>
            </ul>
        </div>
    </div>
</nav>
