title: Checking if value is null before assigning
body: <p>so I am creating a new object and setting its properties from other functions. I need to check if those are null before applying the values. How would I approach this?</p>
  
  <pre><code>Customer = new Customer (
       name = requestCall.Name, 
       age = requestCall.Age.ofType&lt;DateTime&gt;().DOB
      )
  </code></pre>
  
  <p>how would I check if requestCall.Age or requestCall.Name is not null before applying? </p>
