     10  IsConstructor ( argument )
     11 
     12  The abstract operation IsConstructor takes argument argument (an ECMAScript language value).
     13  It determines if argument is a function object with a [[Construct]] internal method.
     14  It performs the following steps when called:
     15 
     16  If Type(argument) is not Object, return false.
     17  If argument has a [[Construct]] internal method, return true.
     18  Return false.
