What is `export type` in Typescript? : <p>I notice the following syntax in Typescript.</p>

<pre><code>export type feline = typeof cat;
</code></pre>

<p>As far as I know, <code>type</code> is not a <a href="https://www.typescriptlang.org/docs/handbook/basic-types.html" rel="noreferrer">built-in basic type</a>, nor it is an interface or class. Actually it looks more like a syntax for aliasing, which however I can't find reference to verify my guess.</p>

<p>So what does the above statement mean?</p>
