I have not had any issues with Traceur. 我与Traceur没有任何问题。 You will not have access to the whole ES6 specification in Traceur (some features such as 'let' are missing) and some experimental features should be disabled for now. 您将无法访问Traceur中的整个ES6规范（某些功能，例如“let”缺失），现在应禁用某些实验性功能。

The usual considerations when switching languages apply. 适用于切换语言时的常见注意事项。 ES6 feels a little bit like CoffeeScript in the sense that the language is not backward compatible. ES6感觉有点像CoffeeScript，因为语言不向后兼容。 You can't just take a piece of uncompiled ES6 and pass it to someone running ES5 because you'll be using arrow functions and other unsupported syntax. 你不能只拿一块未编译的ES6并将其传递给运行ES5的人，因为你将使用箭头函数和其他不受支持的语法。

Traceur compiles to ES5, so IE8 is not supported. Traceur编译为ES5，因此不支持IE8。
