If element exists, do X (jQuery)

Question

I currently do this to check if an elements exists:

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

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

Thanks

Answer 1

if ($(".element1").is('*') || $(".element2").is('*')) {
  ...stuff...
}

EDIT (per comment) Select elements by multiple classes in one call:

if ($(".element1, .element2").is('*') {
  ...stuff...
}
