-<!-- TODO: translation -->Here we have declared a computed property `publishedBooksMessage`. The `computed()` function expects to be passed a [getter function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get#description), and the returned value is a **computed ref**. Similar to normal refs, you can access the computed result as `publishedBooksMessage.value`. Computed refs are also auto-unwrapped in templates so you can reference them without `.value` in template expressions.
+我們在這裡定義了一個計算屬性 `publishedBooksMessage`。`computed()` 方法期望接收一個 [getter 函數](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get#description)，它的返回值是一個**計算屬性 ref**。和一般的 ref 相似，你可以通過 `publishedBooksMessage.value` 来訪問計算的結果。計算屬性 ref 也會在模板中自動解包，所以你可以在模板表達式中引用時而無需添加 `.value`。
 
 Vue 的計算屬性會自動追蹤響應式依賴。它會檢測到 `publishedBooksMessage` 依賴於 `author.books`，所以當 `author.books` 改變時，任何依賴於 `publishedBooksMessage` 的綁定都會同時更新。
