title: date-fns: Difference between parseISO(string) and new Date(string)?
body: <p>I'm trying out date-fns v2.</p>
  
  <p>I got some errors when I ran:</p>
  
  <pre><code>parseISO("Apr 9, 2020, 12:00:00 am");
  </code></pre>
  
  <p>or </p>
  
  <pre><code>parseISO("Apr 9, 2020, 12:00:00 am", "MMM M, YYYY, hh:mm:ss aaaa");
  </code></pre>
  
  <p>but this worked fine:</p>
  
  <pre><code>new Date("Apr 9, 2020, 12:00:00 am");
  </code></pre>
  
  <p>I'm trying to understand when I should use one or the other but I couldn't find the docs for parseISO().</p>
