有什么区别吗
{{ }} 和 ng-bind 的 Angular 。

我对 Angular 很陌生。我从使用 {{ }} 开始，然后在文档中找到了 ng-bind。我认为他们做同样的工作，但为什么需要额外的指令，如果没有，请说出不同之处。

官方文档中有一些提示:https://docs.angularjs.org/api/ng/directive/ngBind

Typically, you don't use ngBind directly, but instead you use the double curly markup like {{ expression }} which is similar but less verbose.

It is preferable to use ngBind instead of {{ expression }} if a template is momentarily displayed by the browser in its raw state before Angular compiles it. Since ngBind is an element attribute, it makes the bindings invisible to the user while the page is loading.
