title: setting a fade to turbo_stream
body: <p>Rails UJS has a compactness about it. In a single line of a <code>js.erb</code> file, one calls the dom_id, a partial AND gives it some interaction (that confirms the change in the object with a minimalist approach).  Example with jQuery library invoked.</p>
  <pre><code>$(&quot;#header&quot;).html(&quot;&lt;%= j render 'header', collection: @trecks %&gt;&quot;).css({ opacity: 0 }).fadeTo('slow',1); 
  </code></pre>
  <p>with the goal of removing UJS and the reliance on jQuery,<br />
  What is the most succinct way to implement an equivalent in vanilla JS of <code>.fadeTo('slow',1)</code> on the turbo stream?</p>
