<blockquote class="note info"><strong class="note-title">Async ans Promises</strong><p>Async calls in LiquidJS are implemented by generators directly, for we can call generators in synchronous manner so this tag implementation is also valid for <code>renderSync()</code>, <code>parseAndRenderSync()</code>, <code>renderFileSync()</code>. If you need to await a promise in tag implementation, simply replace <code>await somePromise</code> with <code>yield somePromise</code> and keep <code>* render()</code> instead of <code>async render()</code> will do the trick. See <a href="/tutorials/sync-and-async.html">Sync and Async</a> for more details.</p>
