</h1>
<div><h2 id="Description">Description</h2>
<div class="description"><p>A reference to the browser's <code>window</code> object. While <code>window</code>
is globally available in JavaScript, it causes testability problems, because
it is a global variable. In angular we always refer to it through the
<code>$window</code> service, so it may be overriden, removed or mocked for testing.</p>
<p>All expressions are evaluated with respect to current scope so they don't
suffer from window globality.</p></div>
