When an object is assigned to a property or variable there will be a
pointer of some kind involved. The question is this : Is that pointer
inside or outside the Value of the property or variable?

The Java specification says clearly [1] that the pointer is inside the
Value. 

The ECMAScript standard says clearly [2] that the pointer is outside
the Value.

It is therefore totally incorrect when talking about ECMAScript to say
that 
  "The value ... is a reference to an Object instance".


[1] The Java Language Specification, Java SE 8 Edition, sec 4.3.1
[2] ECMA 262, v8, sec 6.1
