Javascript undefined object -


I know that a variable is undefined 

  if (typeof (some) = = "Undefined")   
 I do not understand that when a variable is undefined and when an object is undefined For example, when I get a variable i get console.log ()  
  object {detailedView: undefined}   
 My question is why am I not getting this a plain undefined   
 
 
  a  is not undefined It is defined as       
  some  is not defined, so it is  undefined  is.
