提问by SocialCircus
I got thiswhen I was trying to find some way to run my JavaScript programs through terminal. The runand loadcommand mentioned can execute external JavaScript files. Help me how to do this. I am trying to run JavaScript programs which are store locally on my system.
当我试图找到某种方式通过终端运行我的 JavaScript 程序时，我得到了这个。提到的runandload命令可以执行外部 JavaScript 文件。帮助我如何做到这一点。我正在尝试运行本地存储在我的系统上的 JavaScript 程序。
EDIT: I am trying to solve Project Euler Q10 in JavaScript. So this is the program that I want to run in NodeJs or JSC. I need help in running the JavaScript files in Node and JSC. Any example will be really helpful.

Thank You all.
谢谢你们。

Complements of this post, JSC lives at
作为这篇文章的补充，JSC 住在
/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc
and is not in the shell PATHby default. You can fix that with
并且PATH默认情况下不在 shell 中。你可以用
ln -s /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /usr/local/bin
jsctakes filenames as arguments. You could run a file named demo.jswith
jsc将文件名作为参数。你可以运行一个文件名为demo.js与
jsc demo.js
Note that you'll have to use debug()instead of the conventional console.log()in your script to see any output.
请注意，您必须在脚本中使用debug()而不是常规console.log()来查看任何输出。

You're not very clear on what sort of programs these scripts are. Do they do local tasks (e.g. interact with the local file system)? Or are they web scripts that are supposed to interact with (HT|X)ML documents?
您不太清楚这些脚本是什么类型的程序。他们是否执行本地任务（例如与本地文件系统交互）？或者它们是应该与 (HT|X)ML 文档交互的 Web 脚本吗？
If your usage scenario is the former, I recommend using node.js. It is under heavy development, but it is already very usable. For my first project with Node I wrote an XMPP chat bot, completely in JavaScript.
如果你的使用场景是前者，我推荐使用node.js。它正在大力开发中，但它已经非常有用了。在我使用 Node 的第一个项目中，我完全用 JavaScript 编写了一个 XMPP 聊天机器人。

编辑：
I seem to have overlooked "using jsc" in the question and answered "How to run JavaScript on OS X?" instead. Still, I think Node is a better alternative if the author is looking to use JavaScript in place of something like Python or Perl.
我似乎忽略了问题中的“使用 jsc”并回答了“如何在 OS X 上运行 JavaScript？” 反而。尽管如此，如果作者希望使用 JavaScript 代替 Python 或 Perl 之类的东西，我认为 Node 是更好的选择。
