I'm a beginner in JavaScript and lately I've been trying things with RequireJS, I'd like to get some feedback on how good/poor my code is and in what ways it can be improved.My example below is just loading up social plugins - Facebook Like/Share, Twitter Tweet & Google +1. The code is functional and working.index.html:<!DOCTYPE html><html lang=en xmlns=http://www.w3.org/1999/xhtml xml:lang=enxmlns:og=http://ogp.me/ns#xmlns:fb=http://www.facebook.com/2008/fbml>    <head>        <meta charset=utf-8 />        <meta name=viewport content=width=device-width>        <meta name=description' content=Your description here. />        <meta name=keywords content=your, great, keywords />        <title>Your Website Title</title>        <meta property=fb:app_id content=1234567890 />        <meta property=fb:admins content=1234567890 />        <meta property=og:title content=Your Website Title />        <meta property=og:type content=website />        <meta property=og:url content=https://www.your-website.tld/ />        <meta property=og:image content=https://path/to/your/static/logo.png />        <meta property=og:description content=Your description here. />        <meta property=og:locale content=en_GB />        <meta name=twitter:card content=summary>        <meta name=twitter:url content=https://www.your-website.tld/>        <meta name=twitter:title content=Your Website Title>        <meta name=twitter:description content=Your description here.>        <meta name=twitter:image content=https://path/to/your/static/logo.png>        <meta name=twitter:site content=@your-website>        <meta name=twitter:creator content=@your-username>    </head>    <body>        <div id=fb-root></div>        <div id=container>            <div id=header-container>                <header id=header>                    <div class=social>                        <div class=twitter>                            <a href=https://twitter.com/share class=twitter-share-button data-text=Your Name data-via=YourName data-related=OtherName data-hashtags=your-tag>Tweet</a>                        </div>                        <div class='fb-like' data-href=https://www.facebook.com/ data-send=true data-layout=button_count data-width=450 data-show-faces=false data-font=segoe ui></div>                        <div class=plusonec>                            <!-- Place this tag where you want the +1 button to render. -->                            <div class=g-plusone data-size=small data-href=https://www.your-website.tld/></div>                        </div>                    </div>                </header>            </div>        </div>        <script data-main=js/app src=js/lib/require.js></script>    </body></html>js/app.js:requirejs.config({    shim: {      facebook: {        exports: FB      }    },    baseUrl: js/lib,    paths: {      app: ../app,      facebook: //connect.facebook.net/en_GB/all,      facebookLike: lib/facebook/like,      googlePlus: //apis.google.com/js/plusone,      twitter: //platform.twitter.com/widgets    }});requirejs([facebook]);requirejs([facebookLike]);requirejs([twitter]);requirejs([googlePlus]);requirejs([app/main]);lib/facebook/like.js:define([facebook], function(){  FB.init({    appId      : 1234567890,    xfbml      : true  });});app/main.js:define([jquery], function($) { // Unused placeholder});Note: I haven't included jQuery in the require config because it isn't actually used here.
