title: Compare Dates in Angular 2
body: <p>I'm trying to figure out how best to compare dates in Angular 2 and TypeScript 1.8.7.</p>
  
  <p>Given:</p>
  
  <pre><code>startDate: Date;
  endDate: Date;
  
  if(this.startDate.getUTCMilliseconds() === this.endDate.getUTCMilliseconds()){
       //do stuff here
  } else {
       // do something else here
  }
  </code></pre>
  
  <p>This will return an error like "startDate.getUTCMilliseconds is not a function..."</p>
  
  <p>Does somebody have a best practice?  Thanks,</p>
