在带有数组的对象上使用它时，为什么会出现$ parse错误？

Question

I have two json files. I am getting them like this:

var fr, en;
$.getJSON('fr.json', function(data) {
    fr = data;
}).complete(function() {
    ...
});

$.getJSON('en.json', function(data) {
    en = data;
}).complete(function() {
    ...
});

This files are locale files. I want to test them. I want to compare objects fr and en by property names, so unit test will show, when something is missing in locale file.

To get what properties are missing in EN locale I am using this algorithm:

1. Get all object paths, like abc, abe, adx etc in FR locale
2. Then I use $parse(*path*)(fr); and if it returns something -> EN locale has same property as FR locale has.

So my problem. I have such string in file fr. "some": { "numbers": ["one", "two", "three"] ... } In first step, I got such property paths:

some.numbers.0
some.numbers.1
some.numbers.2

And when I am trying to $parse this paths on EN locale I got this error:

Error: [$parse:syntax] Syntax Error: Token '.0' is an unexpected token at column 15 of the expression [addForm.messages.numbers.0] starting at [.0].
http://errors.angularjs.org/1.4.3/$parse/syntax?p0=.0&p1=is%20an%20unexpected%20token&p2=25&p3=some.numbers.0&p4=.0

How can I get working $parse on objects, which contain arrays? Or is there any other way to do what I need?

Answer 1

As @charlietfl mentioned in his comment to the question:

Object doesn't have those properties, numbers is an array. Need to use proper javascript object/array notation

So, I need use

some.numbers[0]
some.numbers[1]
etc 

instead of

some.numbers.0
