If elementone of two elements exists, do X (jQuery)something

I currently do this to check if anone of two elements exists:

if ($(".element1").length > 0 || $(".element2").length > 0) { ...//do stuff... }

Is there a better way to rewrite the same? I mean, ".length"is .length the same as ".length > 0" .length > 0?

Thanks

UPDATE [Added the missing bracket. And the stupid stackoverflow-editing-form does not allow to add less than 6 characters, so I have to write this text]
