TodoMVC (http://todomvc.com/) is a common problem that many developers solve when learning a new language. We'll be tackling TodoMVC in pseudocode for tonight's homework.

Create a Todo app in pseudocode.

A user should be able to:

Add a todo
Edit a todo

GitHub (10 min)

We will be using the GitHub service to share some of our code. We will learn about the underlying technology of GitHub known as git in the next lesson.

Create an account at http://github.com
In a Terminal on your computer, run the following two commands:

git config --global user.name "YOUR NAME"

	function addToQueue(...people) {
	var positions = []

	for (var i = 0; i < people.length; i++) {
	positions[i] = function() {
	return i + 1
	}
	}

	return positions

	* Write pseudocode for a program that allows uses to change a light colour.
	* The light has three different coloured buttons - red, blue and yellow.
	* When a user touches a button, the light changes to that colour.
	* In the selected colour is touched again, make sure the light turns off!
	* If we go overtime, complete the task for homework.
