This figure again shows that every object has a prototype. Constructor
function Foo also has its own__proto__
which is Function.prototype,
and which in turn also references via its__proto__
property again to
the Object.prototype. Thus, repeat, Foo.prototype is just an explicit
property of Foo which refers to the prototype of b and c objects.
var b = new Foo(20);
var c = new Foo(30);
What are the differences between __proto__
and prototype
?
The figure was taken from dmitrysoshnikov.com.
