Comment #1 on issue 164 by kodandersson: Wrong order in Object properties
interation
http://code.google.com/p/v8/issues/detail?id=164
ECMA-262 does not specify enumeration order. The de facto standard is to
match
insertion order, which V8 also does, but with one exception:
V8 gives no guarantees on the enumeration order for array indices (i.e., a
property
name that can be parsed as a 32-bit unsigned integer).
Remembering the insertion order for array indices would incur significant
memory
overhead.
