title: Why do we call $timeout with no delay argument.
body: <p>I am trying to read some angularjs code
  There is a point where the $timeout is been called with no delay parameter.</p>
  
  <pre><code>dataBinding: () =&gt; {
              this.$timeout(() =&gt; {
                  this.selectedRow = null;
              });
          },
  </code></pre>
  
  <p>What is the purpose of that ?</p>
