looking for a shell for Javascript coding/experimenting using command line

Is there a shell for Javascript coding/experimenting using command line offering history, completion, help, debug, etc.? I found iPython very useful for quick Python scripting.

I looked at various shells like node, Rhino, JSDB, but their command line functionality seem to be somewhat limited.

I use kobyk's REPL on cscript.exe.

Also, I use emacs, and there is an elisp module that allows hosting of that REPL in emacs, called jsshell. This means you can do cut/paste, search/replace, command-line editing, and so on - all the text manipulation made available to emacs buffers is available in the interactive Javascript shell. 

Welcome to the JScript shell.
Running JScript Version 5.8.16982

The Firebug console does exactly what you want, as does the Chrome Developer Tools (accessible by pressing F12 or by navigating through the menu).
