title: Is there a downside to using ES6 template literals syntax without a templated expression?
body: <p>Is there a reason (performance or other) not to use backtick template literal syntax for all strings in a javascript source file? If so, what?</p>
  
  <p>Should I prefer this:</p>
  
  <pre><code>var str1 = 'this is a string';
  </code></pre>
  
  <p>over this?</p>
  
  <pre><code>var str2 = `this is another string`;
  </code></pre>
