I read through Waldemar Horwat's Errata and did not find it here:
http://www.mozilla.org/js/language/E262-3-errata.html
here's the spec, including errata:
================================================================
Every built-in function and every built-in constructor has the
Function prototype object, which is the initial value of the
expression Function.prototype (15.3.2.1), as the value of its internal
[[Prototype]]
property.
Every built-in prototype object has the Object prototype object, which
is the initial value of the expression Object.prototype (15.3.2.1), as
the value of its internal [[Prototype]] property, except the Object
prototype object itself.
================================================================
The first paragraph is correct. The second one is not.
The problem is that Object.prototype is not found at 15.3.2.1.
Instead, the link should be to 15.2.3.1
More...
================================================================
15.3.4 Properties of the Function Prototype Object
The Function prototype object is itself a Function object (its
[[Class]] is "Function") that, when invoked, accepts any arguments and
returns undefined.
- 87 -
The value of the internal [[Prototype]] property of the Function
prototype object is the Object prototype object (15.3.2.1).
================================================================
Again, the link should be to 15.2.3.1
It makes it nearly useless when we see a link that does not have context:
================================================================
15.11.6.4 SyntaxError
Indicates that a parsing error has occurred. See 15.1.2.1, 15.3.2.1,
15.10.2.5, 15.10.2.9, 15.10.2.15, 15.10.2.19, and 15.10.4.1.
================================================================
That the spec is written the way it is, and does not use HTML or
hyperlinks seems to make it harder to learn. A good example of a
specification that uses hyperlinks effectively:
http://java.sun.com/docs/books/jls/third_edition/html/j3TOC.html
Other examples would be PHP.net or W3C Specifications (like HTML 4),
although these are more aimed at developers.
