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 MRI Ruby
- therubyrhino - Mozilla Rhino embedded within JRuby
- Node.js
- Apple JavaScriptCore - Included with Mac OS X
- Mozilla Spidermonkey
- Microsoft Windows Script Host (JScript)
A short example:
require "execjs"
ExecJS.eval "'red yellow blue'.split(' ')"
# => ["red", "yellow", "blue"]
