1. DOM

# Write a line of code that will create a button:

var button = document.createElement(button1);

# Write a line of code that will append that button to the document body:

document.appendChild(button1);

# Write a line of code that will give the button a class of 'clicked':

set.attribute("id", "clicked");

# Write code that will give the button a click handler and log 'hello'
# to the console when it is clicked:

document.getElementByTagName("button").onclick = console.log("hello");

# Write code that will give the button a click handler and log **this** button
# object to the console when it is clicked:

button.onclick = showMe

function showMe() {
  console.log("***this***");

# If you type 'this' straight into the console, you will get an object called
# Window. Explain in one sentence what this object is:

2. CALLBACKS

# A fellow student shows you this code.  When he runs it, he expects it to
# wait three seconds, then write "Ding!" to the console.  Instead, it writes
# "Ding!" immediately.  Find the bug and fix it.

function writeDing() {
  console.log('Ding!');
}

var dingHandle = setTimeout (writeDing(), 3000);

3. MISC - ARRAYS AND OBJECTS

# Given the following multi-dimensional array, write the code that will log
# "Eddard" to the console:

var gameOfThrones = [["Joffrey", "Stannis", "Renly"], ["Arya", "Sansa", "Eddard"]];

gameOfTrones[1][2]; = "Eddard"

# Given the following object, write the code that will log "Ramsay" to the
# console:

var gameOfThrones2 = { boltons: ["Roose", "Ramsay"],
             greyjoys: ["Balon", "Theon"]}

console.log(gameOfThrones2[1];

# Write the code that will change "Theon" within the gameOfThrones2 object to "Reek":

I'm thinking I have to iterate over the current value "Theon" to get it to "Reek" but I am not sure how to do that.
