You mean adding an if block to check for the zero and blank string?

[mattmanser]

    fruit = fruit === "" ? "" : fruit || "strawberry";

Woohoo! Javascript rocks! Note that

    fruit = fruit == "" ? "" : fruit || "strawberry";

May or may not be bugged depending on your understanding of a bug and whether you're a marmite fan.

    fruit = fruit === "" && "" || fruit || "strawberrry";

It's flexible too.. though imo your ternary operation is more obvious. ;-)

Personally, I find that once you understand JavaScript, the beauty in what you can do, especially for input validation (which is an ugly, ugly thing) works so well in this language.

And what about the check for 0? Or does the empty string handle that case as well?
