Cocoa (OS X) vs Volt: 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, Volt is detailed as "A ruby web framework where your ruby runs on both server and client". Volt is a ruby web framework where your ruby code runs on both the server and the client (via opal.) The DOM automatically update as the user interacts with the page. Page state can be stored in the URL, if the user hits a URL directly, the HTML will first be rendered on the server for faster load times and easier indexing by search engines.
Cocoa (OS X) and Volt belong to "Frameworks (Full Stack)" category of the tech stack.
"Great community " is the primary reason why developers consider Cocoa (OS X) over the competitors, whereas "Handlebars" was stated as the key factor in picking Volt.
