Scrubby - A Library To Scrub Values In JavaScript, Live

Scrubby is a JavaScript library which allows you to perform JavaScript source transformation to support Bret Victor-style value-scrubbing interfaces with the information without having to recompile code every time the value changes.  Scrubby adds a button to the top-left of the page for each script you specify that's scrubbable. Clicking on that button will open a new window with the code in it, and you can scrub live immediately.

Scrubby works by transforming your code using esprima and escodegen to replace any literal references by a reference into a global table of values. When you scrub a value, scrubby just updates the global table, so the next time your code references that literal, it receives the edited value.  When you scrub a value, scrubby updates the global $values object with the edited value. When the code runs again, it automatically uses the new value.
