jQuery hasClass - check for more than one class

Question

With   if element hasClass  class      I can check for one class  but is there an easy way to check whether  element  has any of many classes   I am using   if element hasClass  class      element hasClass  class           Which isn t too bad  but I am thinking of something like   if element hasClass  class    class2     Which unfortunately doesn t work   Is there something like that
