Why Is `Export Default Const` invalid? : <p>I see that the following is fine:</p>

<pre><code>const Tab = connect( mapState, mapDispatch )( Tabs );
export default Tab;
</code></pre>

<p>However, this is incorrect:</p>

<pre><code>export default const Tab = connect( mapState, mapDispatch )( Tabs );
</code></pre>

<p>Yet this is fine:</p>

<pre><code>export default Tab = connect( mapState, mapDispatch )( Tabs );
</code></pre>

<p>Can this be explained please why <code>const</code> is invalid with <code>export default</code>? Is it an unnecessary addition &amp; anything declared as <code>export default</code> is presumed a <code>const</code> or such? </p>
