title: Template literal inside of the RegEx
body: <p>I tried to place a template literal inside of a RegEx, and it didn't work. I then made a variable <code>regex</code> which holds my RegEx, but it still not giving me the desired result.</p>
  
  <p>However if I <code>console.log(regex)</code> individually, I do receive the desired RegEx, such as <code>/.+?(?=location)/i</code>, <code>/.+?(?=date)/i</code> and so on, but once I place <code>regex</code> inside the <code>.replace</code> it appears not to be working</p>
  
  <pre><code>function validate (data) {
    let testArr = Object.keys(data);
    errorMessages.forEach((elem, i) =&gt; {
      const regex = `/.+?(?=${elem.value})/i`;
      const a = testArr[i].replace(regex, '');
      })
    }
  </code></pre>
