When comparing Cor vs Python (via Skulpt), the Slant community recommends Python (via Skulpt) for most people. In the question“What are the best languages that compile to JavaScript? ” Python (via Skulpt) is ranked 34th while Cor is ranked 42nd. The most important reason people chose Python (via Skulpt) is:
You can write blocking methods that don't cause the whole page to hang, something difficult to do in languages targeting Javascript.
Ranked in these QuestionsQuestion Ranking
Pros
Pro Easy to debug
Cor supports source-maps, allowing you the easy debugging in major browsers. However a line of Cor source is compiled to the exact line number in JavaScript for accurated debugging when developing in platforms that doesn't supports source-maps such as servers.
Pro Clean syntax
Cor enables you to write large applications by providing a clean syntax, classes and a modular architecture to keep organized code, enforcing the writing of readable source code based on conventions.
Pro Cross platform
Cor compiles to plain JavaScript, so, to run it in Node.js or in the browser is piece of cake.
Pro Support coroutines
Cor support coroutines which can be chained, stopped, and synchronized, fitting very well into the web asynchronous world.
Pro Hot reload
Cor provides a smooth front-end development by furnishing a builtin hot-loader which resolves dependences and compiles source code on the fly, with just reloading the Web page. You will only need to use CLI tools to deliver a production-ready version of the app.
Pro Concurrent and parallel
Cor allows to synchronize coroutines by passing messages through channels, and supports the execution of many tasks in parallel, all of that by writing sequential code.
Pro Suspensions
You can write blocking methods that don't cause the whole page to hang, something difficult to do in languages targeting Javascript.
Pro Interactive REPL
You can evaluate new Python code in the browser written by the user.
Cons
Con Work in progress
Cor is still a very much young project (as of November 2015) with just one contributor, few stars on GitHub and virtually no learning resources outside the official documentation.
Con Python 2.6
Skulpt implements an outdated version of the Python language.
