Seven Web Frameworks in Seven Weeks

Key Ideas

We saw a lot of different approaches to constructing apps in this book, but some of the big ideas were these:

• Simplicity

• Where does code run—on the client, a server, or a large cluster?

• Composition—building up things from small pieces

• Declaration over instruction—describing what to do, not how to do it

• Type systems

• State machines

• Interactivity

Let’s recap these key ideas and the frameworks that most embodied them.

Simplicity

Simplicity is a desirable attribute because the human capacity for reasoning about software seems both finite and remarkably limited. Simplicity is often achieved by minimizing or transforming a problem or by focusing on specific parts of a solution. We saw both strategies in this book.
