  --harmony (enable all completed harmony features)
  --harmony_shipping (enable all shipped harmony fetaures)
  --harmony_modules (enable "harmony modules" (in progress))
  --harmony_regexps (enable "harmony regular expression extensions" (in progress))
  --harmony_proxies (enable "harmony proxies" (in progress))
  --harmony_sloppy_function (enable "harmony sloppy function block scoping" (in progress))

  --harmony_object (enable "harmony Object methods")

node.js附带许多默认情况下禁用的功能(因为它们仍在开发中或处于暂存阶段)。 --harmony 标志启用所有已完成的功能。

如何启用所有“进行中”的功能？

Answer 1

您可以查看当前正在“进行中”的标志

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

这篇文章的输出看起来像

--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)

因此您可以轻松地解析它以满足您的需要。
