Yes....  Johnson bridges Ruby to JavaScript.  We haven't released a gem
yet, but you can check it out from github now.  Its pretty stable, and
we only have 1 bug blocking our release.  :-)

  http://github.com/jbarnette/johnson/tree/master

Example:

  context = Johnson::Context.new
  context.evaluate("function foo() { return 'hello world'; }")
  context.evaluate("foo()")  # => 'hello world'
