Sidebar Open By Default on Desktop, Closed on mobile

I'm having some real trouble trying to get my sidebar/navigation content (using Bootstrap) to show (be expanded) by default on desktop and closed by default on mobile and have the icon showing only on mobile. I cannot seem to get this to work.

<nav class="menu menu-open" id="theMenu">
      <div class="menu-wrap">
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
          <i class="fa fa-bars menu-close d-lg-none" id="menu-toggle"></i>
            </button>
          <div id="menu-logo">
            <img src="Final_Logo.png" width="210" height="214" alt="">
          </div>
          <div id="navbarToggleExternalContent">
          <ul id="main-menu">
              <a href="#">Home</a>
              <a href="#">About</a>
              <a href="#">Writing</a>
              <a href="#">Events</a>
              <a href="#">Speaking</a>
              <a href="#">Music</a>
          </ul>
          <ul id="social-icons">
              <li class="facebook"><a href="#"><i class="fab fa-facebook fa-2x"></i></a></li>
              <li class="twitter"><a href="#"><i class="fab fa-twitter fa-2x"></i></a></li>
              <li class="instagram"><a href="#"><i class="fab fa-instagram fa-2x"></i></a></li>
          </ul>
        </div>
      </div>
  </nav>

I have tried using this javascript code, but to no avail:

 $('.menu-close').on('click', function(){
    $('#menuToggle').toggleClass('active');
    $('body').toggleClass('body-push-toright');
    $('#theMenu').toggleClass('menu-open');
    alert("Test");
    });
