title: Usage of the backtick character (`) in JavaScript
body: <p>In JavaScript, a backtick<sup>&dagger;</sup> seems to work the same as a single quote. For instance, I can use a backtick to define a string like this:</p>
  
  <pre><code>var s = `abc`;
  </code></pre>
  
  <p>Is there a way in which the behavior of the backtick actually differs from that of a single quote?</p>

  <p><sup>&dagger; Note that among programmers, "backtick" is one name for what is more generally called the <a href="https://en.wikipedia.org/wiki/Grave_accent" rel="noreferrer">grave accent</a>. Programmers also sometimes use the <a href="https://en.wikipedia.org/wiki/Grave_accent#Use_in_programming" rel="noreferrer">alternate names</a> "backquote" and "backgrave". Also, <a href="https://stackoverflow.com/search?q=back-tick">on Stack Overflow</a> and elsewhere, other common spellings for "backtick" are "back-tick" and "back tick".</sup></p>
