Will be nice when JS gets the Elvis operator and you’ll be able to do ‘if (typeof user?.name === “string”)’ which will have the added value of type narrowing/interaction with ‘never’ if name is expected to be something else.
I'd say the elvis operator would make things worse, especially wrt the parent post.
The problem isn't that `user && user.username` style validation is verbose, but that it's very error-prone. Making it less verbose just means you'll more likely use it before you reach for a better validation strategy, like a declarative validation library.
