title: Removing log statements in Create React App without ejecting
body: <p>I use lots of <code>console.log()</code> statements while developing Apps (and I mean <strong>LOTS</strong>). How exactly can I remove them without <code>"ejecting"</code> from a
  <strong>Create React App</strong> 
  What I considered but not sure how exactly to implement:</p>
  
  <p>In my package.json:</p>
  
  <pre><code> "build": "react-scripts build &amp;&amp; uglifyjs --compress drop_console build/static/js/main.xxxxx.js  -o build/static/js/main.xxxxx.js
  </code></pre>
  
  <p>However How exactly can I know the <code>hash</code> suffix on the <code>main.js</code> file so I can call this command and save the output js file with same filename</p>
