title: TypeScript & JQuery: event in handler "has not" properties 'target' and 'currentTarget'
body: <p>I got <code>TS2339: Property 'target' does not exist on type 'Event'.</code> in below code:</p>
  
  <pre><code>this.$Element.on('click', SELECTOR, (event: JQuery.Event) =&gt; {
      const $ClickedLink: JQuery&lt;HTMLElement&gt; = JQuery(event.target);
      //
  }
  </code></pre>
  
  <p><code>event.currentTarget</code> is also does not exist, as ... defined in JQuery types?</p>
  
  <p>Of course, there are no errors in compiled JavaScript.</p>
  
  <p><strong>This code is not the Angular!</strong> I just combine JQuery and class-based OOP.</p>
