An experiment to detect and remove extraneous leading whitespace from multiline strings, especially for HTML code.
Only tested in latest Firefox, Safari and Chrome (in 2014). Fair warning: this was a personal experiment, might be unstable and have subpar performance.
There isn’t much. See this article for an introduction, and look at the outdent.js file directly.

The demo can be run using PHP’s built-in development server:
