crconsole is a remote Javascript console for Chrome/Webkit that runs in your terminal:

With node.js and the npm package manager:

npm install crconsole -g

You can now use crconsole from the command line.

Start chrome with remote protocol enabled:

google-chrome --remote-debugging-port=9222

$> crconsole
google.com> 1+1
2

There are two extra REPL commands available beyond the standard node.js commands. .tabs lists the open tabs. .switch 2 switches to evaluating in a tab. The argument is the index of the tab to switch to.
