Shim vs. Sham: What is the difference?
提问by garbanzio
What is the difference between a shim an a sham?
shim 和 sham 有什么区别？
Is it enough to include es5-shim.min.js and es6-shim.min.js or should I also include es5-sham.min.js and es6-sham.min.js?
包含 es5-shim.min.js 和 es6-shim.min.js 是否足够，或者我还应该包含 es5-sham.min.js 和 es6-sham.min.js？

According to this Github pagethe shims include all monkey-patches that faithfully represent the ES5 features.
根据这个 Github 页面，垫片包括忠实地代表 ES5 功能的所有猴子补丁。
In other words: you can use the features provided by these files as if you were using ES5 proper.
换句话说：您可以像使用 ES5 一样使用这些文件提供的功能。
The shams, however contain those features that can not be emulated with other code. They basically provide the API, so your code doesn't crash but they don't provide the actual functionality.
然而，shams 包含那些无法用其他代码模拟的功能。它们基本上提供 API，因此您的代码不会崩溃，但它们不提供实际功能。
Which ones do you need? That depends on how you write your code. If you only use features provided by the shims, then include that. If you also want to (optionally) use features from the shams, then you need both of them.
你需要哪些？这取决于您如何编写代码。如果您只使用垫片提供的功能，则包括它。如果您还想（可选）使用 shams 中的功能，那么您需要同时使用它们。
