Ember.js ArrayProxy any() 方法

Ember.js是一个基于模型-视图-控制器（MVC）架构的开源JavaScript框架，用于开发大型客户端Web应用程序。Ember.js是最广泛使用的前端应用程序框架之一，旨在加快开发速度和提高生产效率。目前，许多网站都在使用Ember.js，包括Square、Discourse、Groupon、LinkedIn、Live Nation、Twitch和Chipotle。

any() 方法 会在数组中的每个项目上执行回调，直到找到一个真值。

语法：

any( callback, target );

参数：

callback： 它是将会调用列表每个元素的函数。
target： 它是在回调中调用的目标元素。

返回值： 如果找到真值则返回true，否则返回false。

安装和运行Ember.js的步骤：

要运行下面的示例，您需要有一个Ember项目。要创建一个项目，您首先需要安装ember-cli。在终端中写入以下代码：

npm install ember-cli

现在您可以通过输入以下代码片段来创建项目：

ember new <project-name> --lang en

启动服务器的方法是键入：

ember serve

输入以下代码以生成此示例的路由：

ember generate route any1

import Route from '@ember/routing/route'; 
  
export default class FruitsRoute extends Route { 
    fruits = [
