What is the point of StyleSheet.create : <p>I'm reading the <a href="https://facebook.github.io/react-native/docs/style.html#content" rel="noreferrer">React Native docs / tutorial</a>, and I'm wondering what the point of the <code>StyleSheet.create</code> function is.</p>

<p>For example, the tutorial has the following code:</p>

<pre><code>const styles = StyleSheet.create({
  bigblue: {
    color: 'blue',
    fontWeight: 'bold',
    fontSize: 30,
  },
  red: {
    color: 'red',
  },
});
</code></pre>

<p>But I don't understand the difference between that and:</p>

<pre><code>const styles = {
  bigblue: {
    color: 'blue',
    fontWeight: 'bold',
    fontSize: 30,
  },
  red: {
    color: 'red',
  },
};
</code></pre>
