title: How to output call object in javascript?
body: <p>while I was reading a javascript book, I read the following sentence.</p>
  
  <p>"The call object is initialized with a property named arguments that refers to the Arguments object for the function"</p>
  
  <p>am I allow to output the structure (or values?) of a call object in javascript using console.log or alert() method??</p>
  
  <p>when people say 'a call object', is it a concept or an object?</p>
