Moving from jQuery

Events

// jQuery
$(document).ready(function() {
  // code

I've used promises for quite some time, but ended up going back to nodejs-style callbacks and creating a bunch of higher-order functions that makes handling that easier and reduce the boilerplate code. The two most useful ones, that really made it much easier, deal with error handling/bubbling: (CoffeeScript)

iferr = (errfn, succfn) -> (e, a...) -> if e? then errfn e else succfn a...
throwerr = iferr.bind null, (e) -> throw e


# To let an error bubble up, `iferr` decorates the success function and the error function, and decide which one should handle the response
# This replaces `if (err) return fn err` that you see all over the place

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:

function dog(spec) {

aisamanra

#![feature(unboxed_closures)]
#![feature(core)]
#![feature(io)]

use std::old_io::stdio::{stdin};
use std::collections::HashMap;

// This is our toy state example.
#[derive(Debug)]
struct State {
