This keeps the type in line/sync with the interface, eg if the interface property changes then the type will be updated automatically
<pre><code>interface MyInterface {
 someComplicatedProperty: string | number | object ... 
}

type complicatedType = MyInterface['someComplicatedProperty']

// now complicatedType is equal to string | number | object ...
</code></pre>
