CoffeeScript vs. PureScript vs. RubyMine vs. VBScript Comparison Chart

Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.

Take advantage of the language specific-aware syntax & error highlighting, code formatting, code completion, and quick documentation. Use smart search to jump to any class, file or symbol, or even any IDE action or tool window. It only takes one click to switch to the declaration, super method, test, usages, implementation, and more. Enjoy super fast navigation in your Rails project with an MVC-based project view and model, class, and gem dependencies diagrams. Follow community best practices with code inspections verifying your code for many types of possible errors and providing on-the-fly improvements with quick-fix options. Automated yet safe refactorings help clean up your code and keep it more maintainable. Rails-aware refactorings help you perform project-wide changes: for example renaming a controller will also rename the helper, views, and tests.
