So here we are talking about the module option that will be used by typescript to determine what is the name of the module that will compile your code to the targeted version of javascript you specified with the option target .因此，这里我们讨论的是 typescript 将使用的模块选项，以确定将您的代码编译为您使用选项target指定的 JavaScript 目标版本的模块的名称。

So the underlying question you are asking is, what is my target ?所以你问的根本问题是，我的目标是什么？ Should I target ES3, ES5, ES6, ES7, ES8 or ... ES42 ?我应该针对 ES3, ES5, ES6, ES7, ES8 还是 ... ES42 ？

Answer : the compatibility .答：兼容性。

In 2020 you propably target ES5 or ES6 (which is the default value).在 2020 年，您可能会以ES5或ES6 （这是默认值）为目标。

(You can ignore CommonJS because it relate to ES3 which is 99% chance irrelevant to you) （您可以忽略CommonJS因为它与 ES3 相关，而 99% 的机会与您无关）

If your code is made to be executed on browsers, I would recommand you to look which is the latest version supported by all your targeted browser and take the one that is supported by all.如果您的代码要在浏览器上执行，我建议您查看所有目标浏览器支持的最新版本，并选择所有浏览器都支持的版本。

Ex: Safari ES6, Firefox ES8, Chrome ES8 : so you choose ES6 as target so your code works on every targeted browser.例如：Safari ES6、Firefox ES8、Chrome ES8：所以你选择 ES6 作为目标，这样你的代码就可以在每个目标浏览器上运行。
