Conditional (if, else) in Angular 2
<p>I worked a few years in .NET, Silverlight now I'm starting with Angular 2 and Expressjs.
And I have a doubt that even I could not find how can I do this in angular 2 + Expressjs, and is safe from client side?</p>

<pre><code>&lt;% if(User.Identity.IsAuthenticated){ %&gt;
     &lt;b&gt;Sign Out&lt;/b&gt;
&lt;% } else { %&gt;
     &lt;b&gt;Sign In&lt;/b&gt;
&lt;% } %&gt;
</code></pre>
