Is there a javaScript engine where I can run my code without being forced to use a browser?

Question

Is there any way to write and run a JavaScript code without having a need to run a browser and use its JavaScript engine?

Thanks!

I am amazed no one has pointed this out yet.

Windows includes a Javascript engine that can be used from the command line.

All versions of Windows, since Windows 98, have included something called "The Windows Script Host". It's a windows-standard way to support script "engines". Since the first release, WSH supports JScript, Microsoft's version of Javascript. Among other things, this means that, from a windows command line, you can just invoke the name of any *.js file, and it will run in the JScript engine. (via either wscript.exe or cscript.exe)

You can see this question: What is the ProgId or CLSID for IE9's Javascript engine (code-named "Chakra") to learn how to invoke the higher-performance IE9 Javascript engine from cscript.exe.

I use cscript.exe to run jslint from within emacs, on any .js module I'm editing. (via flymake-for-js) Lots of people use .js modules to do system maintenance or administration.
