title: NodeJS function readFileSync - do I pass "utf8" or {encoding: "utf8"}?
body: <p>I've found various answers to this on Stack Overflow and elsewhere.</p>
  <p>Should I do this:</p>
  <pre><code>let data = fs.readFileSync(FILE_NAME, &quot;utf8&quot;);
  </code></pre>
  <p>Or this:</p>
  <pre><code>let data = fs.readFileSync(FILE_NAME, {encoding: &quot;utf8&quot;});
  </code></pre>
  <p>?</p>
