Why are globals bad?

Question

It totaly makes sense to me to use it here. What would be the alternative? How can i generaly avoid to use them and most of all why is it bad according to jsLint to make us

Answer 1

jsLint is very stringent. It's probably not necessary to get too hung up about it.

But if you feel bad, you can do it just like how you scoped jQuery:

(function($){
  $(function(){
   $.each(somearray ,(function($body){ $body.dosomething() })($('body'));

   if (something){
     $('body').somethingelse();
   }

  });
}(jQuery));
