How can we accomplish it?

• Using an Unobtrusive JavaScript framework, like MooTools or jQuery.
• Ditch Prototype/Scriptaculous.
• One JavaScript file for everything, like "/javascripts/application.js".
• Big modules (classes) eventually need an own JavaScript file.
• JavaScript developers need to think a bit like coders.
• Be smart about your JavaScript, don't produce waste, think about what you want to accomplish.
• Wrong: "I don't know how it will work later, but the coders will find out somehow."
• Work closely with the documentation and don't rely on tutorials that much.
