<p>React Native provides a module that detects the platform in which the app is running. You can use the detection logic to implement platform-specific code. Use this option when only small parts of a component are platform-specific.</p>

<p><code>Platform.OS</code> will be <code>ios</code> when running on iOS and <code>android</code> when running on Android.</p>
<p>There is also a <code>Platform.select</code> method available, that given an object containing Platform.OS as keys, returns the value for the platform you are currently running on.</p>
