title: JSON Parsing error with backslash
body: <p>I have been trying to figure out why the following JSON input will be failed to parse in JSON.parse function.</p>
  
  <pre><code>{"World":"Hello\\Test"}
  </code></pre>
  
  <p>The json above is being returned by JSON.NET.</p>
  
  <p>I have tried multiple methods to get this working. As you can see the backslash is escaped and <a href="https://jsonlint.com/" rel="noreferrer">https://jsonlint.com/</a> is able to parse it.</p>
  
  <p>I have a failing sample at <a href="https://jsfiddle.net/ckp0uc0p/3/" rel="noreferrer">https://jsfiddle.net/ckp0uc0p/3/</a> as well.</p>
  
  <p>Any help will be appreciated.</p>
