How do I get a Javascript runtime interpreter installed on OS X?
提问by wide_eyed_pupil
With OS X Xcode installed one can run ruby code in terminal with ">ruby somefile.rb" command (or from inside TextWrangler with the run command). You can also run a ruby interpreter from in terminal and type code in single lines while the interpreter retains variable objects.
安装 OS X Xcode 后，可以使用“>ruby somefile.rb”命令（或使用 run 命令从 TextWrangler 内部）在终端中运行 ruby 代码。您还可以在终端中运行 ruby 解释器并在解释器保留变量对象的同时在单行中键入代码。
Want same possibilities for Javascript. What must I install (if anything) on OS X to have that functionality? Not looking for an IDE as such just an interpreter that will run in Terminal.app?
想要 Javascript 的相同可能性。我必须在 OS X 上安装什么（如果有的话）才能拥有该功能？不寻找这样的 IDE 只是一个将在 Terminal.app 中运行的解释器？
I assume this is an allowed question for Stackoverflow based on other allowed questions about IDEs for various languages like: What's a good IDE for Python on Mac OS X?
我认为这是 Stackoverflow 允许的问题，基于其他有关各种语言的 IDE 的允许问题，例如： Mac OS X 上 Python 的好 IDE 是什么？

There is a Javascript interpreter in the JavaScriptCore framework that comes with OS X. The interpreter is called jsc and can be found at the following path:
OS X自带的JavaScriptCore框架中有一个Javascript解释器，这个解释器叫做jsc，可以在以下路径找到：
/System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc
There is a built-in function, quit(), which will exit interactive mode.
有一个内置函数 ，quit()它将退出交互模式。
If you want to make it easier to use I suggest creating a symlink to a location in your path, e.g.:
如果您想让它更易于使用，我建议创建指向路径中某个位置的符号链接，例如：
sudo ln -s /System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc /usr/local/bin
This will put a symbolic link in /usr/local/bin.
这将在/usr/local/bin.

Node.js. It's the V8 engine + libraries + REPL.
节点.js。它是 V8 引擎 + 库 + REPL。
Although Node is usually used for web/network-related applications, at its core it's just a plain JS engine and can even be used for shell scripting.
虽然 Node 通常用于 web/网络相关的应用程序，但它的核心只是一个普通的 JS 引擎，甚至可以用于 shell 脚本。
You can install it from the installer, brewor just ./configure && makefrom a Node.js' tarball.
你可以安装它从安装程序，brew或者只是./configure && make从一个Node.js的压缩包。
There's also Rhino.
还有犀牛。

You have two options:
您有两个选择：
Use console in your Browser: Browsers such as chrome,safari, firefox come buildtin with console which are cappable of running javascript. to open open console on chrome. Press CTRL+ SHIFT+ J
Install Nodejs: As others have pointed out, try http://nodejs.org/using which you can run javascript in terminal app similar to irb
在浏览器中使用控制台：chrome、safari、firefox 等浏览器自带控制台，可以运行 javascript。在 chrome 上打开打开的控制台。按CTRL+ SHIFT+ J
安装 Nodejs：正如其他人所指出的，尝试使用http://nodejs.org/可以在类似于 irb 的终端应用程序中运行 javascript
