The future is here: Classless object-oriented programming in JavaScript.

Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.

Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.

I think it's really, really sleek, and this is what it looks like:

• cpr => (require ... :reload)
• cpR => (require ... :reload-all)

Evaluation

• :Eval (clojure code) => runs (clojure code) in repl
• cpp => evaluate inn-most expessions under cursor
• cp<movement> => evaluate text described by <movement>
• cqp => opens quasi-repl
• cqc => quasi-repl command line window
