Especially when I want to change only [[Prototype]] and keep values of
other internal properties and methods for that object.
And I have a question. Why ES5 give control on values of internal
attributes? What will improve that? "Save" augmentation of built-in?
Good design of JS libraries?
Instead of that I want just naming convention improvements + `const`
keyword as Mozilla implement.
For example:
myObj.CONSTANT = 3.14;
And I expect property `CONSTANT` to have internat attributes
{DontDelete), {ReadOnly}. But I forgot, Crockford suggest upper case
only for global variables.
If they was added new loop, misconseptions of JS library authors will
be gone away. For example if there is:
for own(var i in obj) {
//do something with next own property
}
And my last question is. Why do you change terminology in ES5? What
was wrong with ES3 terminology?
