这是Visual Studio 2015的Angular 2最终版应用程序。 gulp用于从节点模块生成库
我的应用在Chrome和Edge中运行良好，但在Firefox和IE中无法正常工作

Firefox错误：

我尝试了很多来解决这个问题，但仍然没有工作，请指导我解决同样的问题。 我认为它是一个tsconfig文件问题。 这个应用程序在chrome中正常运行，同样的代码在system.src文件中生成错误，以加载所有模块和bootstrap（main.ts）文件

你的目标是“目标”：“es6”。
Firefox还不支持完全ES6，你可以在这里看到：
以下功能（部分）在Firefox中实现，但不符合规范。这有几个可能的原因：Firefox的实现基于ES6规范的较旧草案，或者Firefox的当前实现是在将类似功能添加到ES6规范之前添加的实验设计。
您可以将目标更改为ES5以确保兼容性。
希望这有帮助

出现此问题是因为您在for..of循环中使用了 const 关键字（here）。 这绝对是有效的声明，但它在Edge中不起作用（不用Firefox测试）。所以我认为，将所有事件更改为让
会更好
