title: Null coalescing operator in React JS/ Typescript
body: <p>We have the Null coalescing operator in <code>.NET</code> and we can use as below</p>
  
  <pre><code>string postal_code = address?.postal_code;
  </code></pre>
  
  <p>Same thing can we do in React JS?</p>
  
  <p>What i found like we can do with &amp;&amp; operator</p>
  
  <p>in <strong>address.ts</strong> file</p>
  
  <pre><code>string postal_code = address &amp;&amp; address.postal_code;
  </code></pre>
  
  <p>what i need like .net feature is possible in typescript with react JS, is that possible ?</p>
  
  <p>something like:</p>
  
  <pre><code>string postal_code = address?.postal_code // I am getting the error in this line if I try to use like .NET
  </code></pre>
