Given what we've learned about under- and over-abstraction, we can say that a balanced abstraction is one that sits neatly in between these two undesirable opposites. The skill of creating a balanced abstraction is both an art and a science, and requires that we have a very good understanding of both the problem domain and the user's capabilities and intents. By employing many of the principles and warnings in this chapter, we can hope to remain balanced in our code building. For the previous example of a GalleryComponent, we should, once again, explore the requirements of the abstraction:
- The ability to display one or more images
- The ability to display captions alongside images
- The ability to control the dimensions ...
