title: why prefix "<any>" before window object?
body: <p>I'm new to typescript, I saw a book that has below statement:</p>
  
  <pre><code>(&lt;any&gt;window).model= ...;
  </code></pre>
  
  <p>I'm confused, what's the name of syntax by adding <code>&lt;any&gt;</code> before a variable and what's the benefits doing that?</p>
