This post doesn't make much sense to me either. JavaScript encourages an object-oriented style, but with prototype-inheritance and flexible method binding (where `this` in a function is determined by the caller). CoffeeScript's features embrace both of these design choices and make them easier to use. Using the `class` keyword to set up a prototype chain is really nice, and `@` opens up whole new possibilities that would have been too syntactically heavy with the `this` keyword. JS is object-oriented. If you really want to write functional code in JS, you're going to need persistent data structures, like Clojure (and presumably ClojureScript) provide. Otherwise you'll pay a high cost for constantly copying objects. Without persistent data structures you pretty much need to mutate properties to remain performant. And if you're mutating properties, object-oriented code is a good approach. I don't understand why the author sees randomly assigning functions to anonymous objects as a superior approach to using prototypes.
