title: How to write a RegEx finding ` (Grave accent) surrounding a string not containing ${ variable }
body: <p>I need a regular expression that finds <em>grave accents</em> that surround a string, but not if that string contains <code>${ someVar }</code>.</p>
  <pre class="lang-js prettyprint-override"><code>const twoMatch = `test string`;
  const noMatches = `test ${ variabel }`;
  
  </code></pre>
  <p>This would be good to easily replace the grave accents with regular apostrophes.</p>
