title: Down-side on calling async function without await
body: <p>Given the code with async</p>
  
  <pre><code>async function wierdFunction(){
      setTimeout(function(){
          //background process that does not return
          //Russian roulette
          if ( Math.random() &gt; 0.99 )
              throw new Error('Bang!');
      }, 3000);
  }
  </code></pre>
  
  <p>I only need to call this function asynchronous, I don't need to know when it finished.</p>
  
  <pre><code>app.post('/wierd-endpoint', function (req,res){
      wierdFunction();
      res.json({status:"Running. Now, go away."});
  });
  </code></pre>
  
  <p>Is there any advise against calling it without <code>await</code> keyword?</p>
