jquery - remove class but not selector class in jquery

Question

I want to remove class from div but selector class like: I want to remove only 'check' from below div.

Note: class name are dynamic. Its name can be anything.

<div class="pop check"></div>
$(function(){
$('.pop').not('pop').removeClass()  // not working
})

working code

$(function(){
$('.pop').removeClass().addClass('pop')
})

Is there any better way to do this
