Angular：对象结构的最佳实践(Angular: object structure best practice)

 我在Angular工作，目前专注于过滤嵌套对象。 这是我的对象的结构： 
 
$scope.subjectBin = {
     "Faculty of Engineering": {
           "ECE": [{<course-object>},{<course-object>}],
           "CHEM: [{<course-object>}]
      },
     "Faculty of Science": {
           "BIOL: [{<course-object>},...],
           ...
      },
      ...
}
 
 当我使用过滤这个对象，构建新功能，并在分层手风琴中呈现它时，我想我应该改变这个对象的设计。 
 
 有人建议将对象更改为以下内容： 
 
$scope.subjectBin = [{
    faculty: "Faculty of Engineering",
    subjects: [{
        subjectName: "ECE",
        courses: [{<course-object>},{<course-object>}]
        },
        ...
    ]
}, {
    faculty: "Faculty of Science",
    subjects: [{
        subjectBin: "CMPUT",
        courses: [{<course-object>},...]
        },
        ...
    ]
}]
 
 我被告知这种布局更好，因为：“它不使用对象作为键盘图，它遵循一种模式”。 
 
 我同意它更好，但总体上希望对对象布局做一些澄清。 
 
 布置嵌套对象的 最佳做法是什么？ 具有固定键名的基于数组的对象是否更可取？ 

I'm working in Angular, currently focusing on filtering a nested object. Here is the structure of my object:
 
$scope.subjectBin = {
     "Faculty of Engineering": {
           "ECE": [{<course-object>},{<course-object>}],
           "CHEM: [{<course-object>}]
      },
     "Faculty of Science": {
           "BIOL: [{<course-object>},...],
           ...
      },
      ...
}
 
As I work with filtering this object, build new features, and render this in a layered accordion, I'm thinking I should change the design of this object. 
 
Someone suggested to change the object to the following:
 
$scope.subjectBin = [{
    faculty: "Faculty of Engineering",
    subjects: [{
        subjectName: "ECE",
        courses: [{<course-object>},{<course-object>}]
        },
        ...
    ]
}, {
    faculty: "Faculty of Science",
    subjects: [{
        subjectBin: "CMPUT",
        courses: [{<course-object>},...]
        },
        ...
    ]
}]
 
I was told this layout is better because: "it doesn't use objects as keymaps and it follows a pattern". 
 
I agree that it's better but would like some clarification on object layout, in general.
 
What are best practices for laying out nested objects? Are array-based objects with fixed key-names preferable?
