title: What is this new syntax gql`string`
body: <pre><code>const GET_DOGS = gql`
    {
      dogs {
        id
        breed
      }
    }
  `;
  </code></pre>
  
  <p>I found this new syntax from <a href="https://www.apollographql.com/docs/react/essentials/queries.html" rel="noreferrer">here</a>. </p>
  
  <p>Can you explain this syntax? Where can I find detail about it? </p>
