Typically `||` is sufficient. Yes if you want to allow empty strings and/or 0, you would need to add checks for those to the left of the `||`, but I'm not sure that's a bad thing to require in JavaScript.
The nullish conditional operator, however ( `?.` and `?[`) , I think is a bigger addition to the language.
