title: Explain about async/ await in Protractor
body: <p>I'm new to protractor. How does async/await in this function works? Can anybody explain it to me?</p>
  
  <pre><code>it('TC_01 - Verify Home page title', async () =&gt; {
      await headerPage.waitForTitleContain('Homepage', 30000);
      await expect(headerPage.getTitle()).toEqual('Homepage');
  });
  </code></pre>
