title: Parallel stringify (serialize) to JSON in javascript
body: <p>In my react-native app I need to stringify (serialize) big objects and not to block js thread - asynchronous api that uses another threads, something like this:</p>
  <pre><code>JSON.stringifyAsync({ foo: &quot;bar&quot; }).then(x =&gt; console.log(x));
  </code></pre>
  <p>Please don't suggest to wrap JSON.stringify into Promise, it just defers blocking of js thread.</p>
