-给定一个对象，用来表示部分音乐专辑收藏。 每张专辑都有几个属性和一个唯一的 id 号作为键值。 并非所有专辑都有完整的信息。
+You are creating a function that aids in the maintenance of a musical album collection. The collection is organized as an object that contains multiple albums which are also objects. Each album is represented in the collection with a unique `id` as the property name. Within each album object, there are various properties describing information about the album. Not all albums have complete information.
 
-以 `updateRecords` 函数开始，这个函数需要一个对象 `records`，包含一个音乐专辑集合，一个 `id`，一个 `prop`（如 `artist` 或 `tracks`），和一个 `value`。 使用下面的规则完成函数来修改传递给函数的对象。
+The `updateRecords` function takes 4 arguments represented by the following function parameters:
 
--   函数必须始终返回整个音乐专辑集合对象。
--   如果 `prop` 不是 `tracks` 并且 `value` 不是一个空字符串， 将专辑的 `prop` 更新或设置为 `value`。
--   如果 `prop` 是 `tracks` 但专辑没有 `tracks` 属性，则应创建空数组并为其添加 `value`。
--   如果 `prop` 是 `tracks` 并且 `value` 不是一个空字符串，将 `value` 添加到专辑现有 `tracks` 数组的末尾。
--   如果 `value` 是空字符串，从专辑里删除指定的 `prop`。
+-   `records` - an object containing several individual albums
+-   `id` - a number representing a specific album in the `records` object
+-   `prop` - a string representing the name of the album’s property to update
+-   `value` - a string containing the information used to update the album’s property
 
-**注意：** 用 `recordCollection` 对象做为测试参数对象。
+Complete the function using the rules below to modify the object passed to the function.
+
+-   Your function must always return the entire `records` object.
+-   If `value` is an empty string, delete the given `prop` property from the album.
+-   If `prop` isn’t `"tracks"` and `value` isn't an empty string, assign the `value` to that album’s `prop`.
+-   If `prop` is `"tracks"` and `value` isn’t an empty string, add the `value` to the end of the album’s existing `"tracks"` array.
+-   If the album doesn’t have a `"tracks"` property, create a new array for the album's `"tracks"` property before adding the `value` to it.
+
+**Note:** A copy of the `recordCollection` object is used for the tests. You should not directly modify the `recordCollection` object.
