How can i check for null using a ternary operator in react?

I have the following:

  const myuser = userList.filter(itm => itm.user.Id == Id)
  const email = myuser.length > 0 ? myuser[0].user.email : "";

The issue is that user can be null and the line itm.user.Id will fail

How can i use a null check as a ternary operator ?

>Solution :

You can use optional chaining. So this won’t fail if you use
itm?.user?.Id == Id.

Just make sure to check that myuser actually has a value afterwards.
