Question

Maybe somebody can advise what tool, approach, reference I can use to achieve the following goals for a large web application when it comes to JavaScript: reusability, bundling, unit testing, many developers, stuff like that. For example I've checked out browserify tool but there's practically no documentation, no book nothing.
