Aura vs Cocoa (OS X): What are the differences?
Developers describe Aura as "Modern tools for modern applications". The Aura project centers around a collection of high-quality, well-tested, semantically versioned, standards-compliant, independent library packages that can be used in any codebase. On the other hand, Cocoa (OS X) is detailed 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.
Aura and Cocoa (OS X) belong to "Frameworks (Full Stack)" category of the tech stack.
Aura is an open source tool with 2.99K GitHub stars and 269 GitHub forks. Here's a link to Aura's open source repository on GitHub.
