A comment on Binary File Parsing revisited using Javascript.

Re:Binary File Parsing revisited using Javascript by spacejunkie on Thursday August 18, 2011 @10:57PM (#2902046)
It seems that this library relies on hash keys being returned in the same order that they appear in a literal hash constructor. I.e., if var x = { "b":3, "a":10 }, then for (n in x) will _always_ assign n to "b" first before assigning it to "a".

Is this something that is guaranteed by javascript?

All the browsers use the correct order for non integer keys. So unless you name your key "123" it will work.

See this bug report for more lengthy details http://code.google.com/p/v8/issues/detail?id=164

In theory? No. In practice? ... Still no, if you use delete.
