You can re-use an interface's property by extracting it using normal object access notation eg
<pre><code>interface SomeInterface {
 usefulProperty: string | object {}
}

type newType = SomeInterface['usefulProperty']

// now newType is equal to string | object {}
</code></pre>Not only can this save you having to type out stuff twice, but more importantly, should SomeInterface&gt;usefulProperty change, then newType will automatically change.
