我注意到对象的 ECMAScript 定义已从第 3 版更改为第 5 版和第 6 版。

第三版

4.3.3 Object
An object is a member of the type Object. It is an unordered collection of
properties each of which contains a primitive value, object, or function. A
function stored in a property of an object is called a method.

第五和第六版

4.3.3
object
member of the type Object.
NOTE An object is a collection of properties and has a single prototype
object. The prototype may be the null value.

既然它不再说属性的无序集合,这是否意味着它们现在是有序的?也适用于 JavaScript?
