node.js带有许多默认情况下处于禁用状态的功能（因为它们仍在开发中或正在分阶段）。该--harmony标志启用所有已完成的功能。

如何启用所有“进行中”功能？

阿尔贝托·扎卡尼（Alberto Zaccagni）

您可以看一下当前正在“处理”哪些标志

node --v8-options | grep "in progress"

截至本文的输出看起来像

--harmony_modules (enable "harmony modules" (in progress))
--harmony_array_includes (enable "harmony Array.prototype.includes" (in progress))
// ...
// (I've removed the other lines, which look like the above)

因此，您可以轻松地对其进行解析以适合您的需求。
