Clean Up Your Code with Optional Chaining
February 10, 2026
If you find yourself writing lengthy defensive checks like `if (data && data.user && data.user.profile)` just to safely access a deeply nested property, stop! Modern JavaScript introduced Optional Chaining (`?.`) specifically for this scenario. Now you can write `data?.user?.profile?.name`. If any part of that chain is null or undefined, the expression simply evaluates to `undefined` instead of throwing a massive runtime error. It’s cleaner, safer, and makes your data access logic much more readable immediately.
