title: Is there a JS equivalent for C# "?." operator?
body: <p>What I'm looking for is actually a shortcut for JS
      <code>obj.fn &amp;&amp; obj.fn();</code>
  code. One of the reasons for that is sometimes the <code>obj.fn</code> part might be quite long.</p>
  
  <p>C# uses the <a href="https://docs.microsoft.com/en-gb/dotnet/csharp/language-reference/operators/null-conditional-operators" rel="nofollow noreferrer">Null Conditional Operators</a> for that: <code>obj?.fn()</code></p>
