ECMA 6虽然启用了实验性js，但不起作用 [英] ECMA 6 Not working although experimental js is enabled

问题描述

首先，请原谅我的不好的英语。

我有最新的Chrome版本，启用了实验Javascript标志。我想使用ECMA6，但它不工作。我不知道为什么有没有任何技巧或其他标志也必须启用？ ECMA6的每个保留字（如导入，类或其他）会引发未捕获的语法错误：意外的保留字错误。

我将非常感谢任何帮助。而且，因为我几个月前问这个问题，而是没有得到任何答案，但使用ECMAScript 6 a>，不是。这不能解决我的问题。

谢谢。

我想使用模块，因为我喜欢更多的ecma6模块，而不是使用Require或Common。而且我也喜欢类的糖语法，代码看起来更好:)
我正在运行Chrome 45（及其更新版本），还有Chrome Canary（在版本47中）。他们都启用了启用实验Javascript标志。

在Chrome Canary中，控制台中出现的错误不同的：未捕获的SyntaxError：意外的令牌导入，而在Chrome中它会抛出意外的保留字。

解决方案

尚未在任何浏览器中本地支持。您将需要使用透明机，例如 Traceur 或 Babel 。查看以下其中一个以帮助您开始使用：

• 选择ES6模块今天！



li> 使用webpack编写客户端ES6

对于类，您可以使用这些本机，而无需经历一个透析器。您可以在此查看兼容性表，查看哪些浏览器今天支持本机：

截至目前，您可以看出，大多数浏览器还没有支持本地的类。但是，如果您使用的是Babel或Traceur，那不应该是一个问题。

First of all... excuse my bad english.

I have the latest Chrome version, with the Experimental Javascript flag enabled. I want to use ECMA6, but it doesn't work. I don't know why. Is there any trick or other flag that must be enabled too? Every reserved word of ECMA6 (like import, class, or whatever) throws an "Uncaught SyntaxError: Unexpected reserved word" error.

I will appreciate any help. And, because i ask this a few months ago without getting any answer but "possible duplicate" of this Using ECMAScript 6 , it is not. It does not solve my problem.

Thanks.

--- EDIT --- I want to use modules, since i like more the ecma6 modules than using Require or Common. And i also like the sugar syntax of classes, code looks better :) I'm running Chrome 45 (and its updated), and also Chrome Canary (which is in version 47). Both of them with the flag "Enable Experimental Javascript" enabled.

-- EDIT 2 -- In Chrome Canary, the error that appears in the console it's different: "Uncaught SyntaxError: Unexpected token import", while in Chrome it throws an "Unexpected reserved word".

解决方案

Modules are not yet natively supported in any browser. You will need to use a transpiler such as Traceur or Babel. Take a look at one of the following to help you get started:

• Choose ES6 modules Today!
• ES6 In Depth: Using ES6 today with Babel and Broccoli
• Writing client-side ES6 with webpack

As for classes, you may be able to use these natively without having to go through a transpiler. You can check the compatibility table here to see which browsers support classes natively today:

As of right now, you can see that the majority of browsers do not yet support classes natively. However, if you are using Babel or Traceur, that shouldn't be a concern.
