Cocoa (OS X) vs Apache Cocoon: What are the differences?
Developers describe Cocoa (OS X) as "The Cocoa frameworks consist of libraries, APIs, and runtimes that form the development layer for all of OS X". Much of Cocoa is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employs a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa applications. On the other hand, Apache Cocoon is detailed as "*A web development framework built around the concepts of separation of concerns *". It is a web development framework built around the concepts of separation of concerns (making sure people can interact and collaborate on a project, without stepping on each other toes) and component-based web development.
Cocoa (OS X) and Apache Cocoon belong to "Frameworks (Full Stack)" category of the tech stack.
