+<h1>Obvious Javascript 'Injection' Fallback</h1>
+<p>2020-12-04</p>
+<p>Sometimes websites and web apps might require content to be "injected" via Javascript. I should mention that I am strongly against this practice - but often this kind of thing is out of one's hands. So, the least I can do is setup these "injections" to have proper fallbacks for users who disable JS. You would be surprised how many developers build <em>empty</em> HTML elements with the assumption they will be filled via Javascript.</p>
+<h2>Our Hypothetical Project</h2>
+<p>Let's pretend that we have a total tally that pulls in the number of current users using our fake SaaS app. We would do something like this:</p>
+<h3>HTML</h3>
+<p>Here we create an empty <code>h2</code> tag that will update with the current number of users via js:</p>
+<pre><code>&lt;main&gt;
+ &lt;h2 class=&quot;total-tally&quot;&gt;&lt;/h2&gt;
+&lt;/main&gt;
+</code></pre>
+<h3>Javascript</h3>
+<p>You'll have to use your imagination here and assume that the <code>totalTally</code> variable pulls in the numbers dynamically via API:</p>
+<pre><code>var totalTally = &quot;273,677&quot; /* This would pull something dynamically in prod */
+document.getElementsByClassName(&quot;total-tally&quot;)[0].innerHTML=totalTally;
+</code></pre>
+<h2>The Problem</h2>
+<p>The big issue we have now occurs when a user visits this page without JS enabled. The <code>h2</code> tag will remain empty and they won't see anything. I know this seems like a very avoidable issue, but you would be surprised how often it actually happens on the web.</p>
+<h2>The (overly simple) Solution</h2>
+<p>The easiest way to avoid these types of empty tags - add static content. I know - mind blowing, right?</p>
+<h3>HTML (updated)</h3>
+<pre><code>&lt;main&gt;
+ &lt;h2 class=&quot;total-tally&quot;&gt;200,000+&lt;/h2&gt;
+&lt;/main&gt;
+</code></pre>
+<p>You might be reading this and saying to yourself, "Wow! Thanks Captain Obvious!" and that's a fair reaction. This is an <em>obvious</em> demo on purpose. If even one single reader learns to avoid leaving empty HTML tags that are solely dependent on Javascript injection, then I'd say this demo was a huge success.</p>
+<p>Rule of thumb: don't make assumption about your users. Play it safe.</p>
