我没有经验嵌入PowerShell中，但我会以为这是很像的IronPython的，它的最终深深地连接到CLR。

I don't have experience embedding Powershell, but I'm going to assume it's a lot like IronPython in that it's ultimately deeply connected to the CLR.

所以：

PowerShell中/ IronPython的

我想组这两个在一起，说的大的利好是直接能够通过CLR进行通讯。

I would group these two together and say the big positive is direct ability to communicate via the CLR.

的底片，这些可能是内存使用，并可能运行时的性能。虽然因为它将运行在CLR已经无论如何，它不应该有太大的差别。

The negatives for these may be memory use and possibly runtime performance. Although since it will be running in the CLR already anyway, it shouldn't be much of a difference.

的Lua / Javascript的

相似的两者会使用某种形式的P /最终调用API嵌入。 （或COM互操作）

Similar in that both would be embedded using some sort of P/Invoke API ultimately. (Or COM Interop)

优点：速度快，使用更少的内存。 缺点：P /调用，不受管理的code等。

Pro: Fast, less memory usage. Con: P/Invoke, unmanaged code, etc.

之间的Lua和Javascript：

Between Lua and Javascript:

Lua中甚至可能更快，不到Javascript的内存猪，但JavaScript有更熟悉的OOP和FP成语烤成的语言。

Lua may be even faster and less of a memory hog than Javascript, but Javascript has more familiar OOP and FP idioms baked into the language.
