Keep Dependencies Local as Possible

This is general good design principle to make it easier to:

• Add new features

• Remove old features

The general ideas is to group the specific code and resources for a feature in one spot rather than have designs which scatter the resources across many places.

For instance if you have a new screen that requires some javascript code and an HTML template then a design of putting all of these resources into a self-contained directory is an easier pattern for other programmers to follow when they add a screen.

But perhaps even more importantly it becomes obvious when code is no longer needed. So it makes it easier to eliminate dead code.

The same idea can be used in home organization.
