什麼時候支持ng-if和ng-show / ng-hide？ - When to favor ng-if vs. ng-show/ng-hide?

問題：

I understand that ng-show and ng-hide affect the class set on an element and that ng-if controls whether an element is rendered as part of the DOM. 我知道ng-show和ng-hide會影響元素上設置的類，並且ng-if控制元素是否呈現爲DOM的一部分。

Are there guidelines on choosing ng-if over ng-show / ng-hide or vice-versa? 是否有關於選擇ng-if不是ng-show / ng-hide或相反的指南？
