// ES6 for loops
// =============

// Things in ES6 can be "iterable". Arrays are iterable by default.

var fruits = ['Apple', 'Banana', 'Grape'];

for (var fruit of fruits)
  console.log('Fruit: ' + fruit);

// ES6 destructuring
// =================

// Assume a Person "class".

Person.prototype.giveTwoThings = function() {
  return ['This', 'That']
}

// var [a, b] = p.giveTwoThings()

// ES6 method parameter changes
// ============================

// Default argument values are possible in ES6.

var Person = function(name = 'John Doe') {
  this.name = name;
};

// var p = new Person();

// ES6 classes example
// ===================

// Currently, with prototypal inheritance:

var Person = function(name) {
  this.name = name;
};

Person.prototype.talk = function(words) {

The idea is you can still use Backbone.View to structure components in the screen. Run the code below with each page render.

In CoffeeScript:

$ ->
  for el in $('[data-view]')
    $el = $ el
    viewName = $el.data 'view'
    view = window[viewName]

new view(el: el) if view?

# Storing a Backbone.Model in localStorage
# ========================================
# 
# You can then use localStorage as a collection. For an usage example, see
# https://github.com/juliocesar/factory/blob/master/coffeescripts/factory.coffee#L149
# This largely Just Worked™ for my needs. YMMV!

    class MyModel extends Backbone.Model

# Simplest (?) console action parsing that doesn't use gems.
# The idea, in a nutshell:
# 
# $ mycommand foo 
# 
# * Calls `foo` or a default method as per the ACTIONS constant (see below).
#
# $ mycommand foo bar
#
# * Calls `foo` with "bar" as a parameter.
