title: Invisible backslash in Javascript
body: <p>It might be a stupid question, but I really need to know. Why JS doesn't see a single backslash?</p>
  
  <p>For example:</p>
  
  <pre><code>console.log("\");
  </code></pre>
  
  <p>Gives me nothing, but when I add one more backslash, then it shows"\".</p>
  
  <p>Why is that?</p>
