ExecJS

ExecJS lets you run JavaScript code from Ruby. It automatically picks the best runtime available to evaluate your JavaScript program, then returns the result to you as a Ruby object.

ExecJS supports these runtimes:

therubyracer - Google V8 embedded within Ruby for exceptional performance
Google V8
Node.js
Apple JavaScriptCore
Mozilla Spidermonkey
TODO Mozilla Rhino
TODO Microsoft Windows Script Host (JScript)

A short example:

require "execjs"
ExecJS.eval "'red yellow blue'.split(' ')"
# => ["red", "yellow", "blue"]
