If you are tired of writing long, defensive logic like 'if (user && user.profile && user.profile.name)' to avoid crashing your app, it is time to embrace optional chaining. By using the '?.' operator, you can simply write 'user?.profile?.name'.

If any part of that chain is null or undefined, the expression gracefully returns undefined instead of throwing a nested property error. This syntax makes your JavaScript or TypeScript code significantly more readable and resilient when dealing with deeply nested data from external APIs.
