What's the difference between alignItems and alignSelf in React Native?
<p>I am trying to understand the FlexBox implementation on React Native and find it very unfortunate that <a href="https://facebook.github.io/react-native/docs/flexbox.html" rel="noreferrer">Facebook's documentation</a> doesn't provide any info at all on what the individual properties mean. They only name the ones that they have implemented without further documentation...</p>

<p>I love the <a href="http://flexboxin5.com/" rel="noreferrer">Flexbox in 5</a> tutorial, it does an amazing job in explaining the most important FlexBox properties. However, there is no mention of the <code>alignSelf</code> property there and I also didn't find documentation about this one elsewhere...</p>

<p>Can someone explain (maybe even demonstrate visually) what the difference between the two is? I also appreciate links to any resources that explain the React Native FlexBox properties in more detail and provide some guidance in using them.</p>
