To save your work, click the green button in the bottom right-hand corner. You can always come back and re-edit your gist.

1. Documentation and Googling (75 min)

Documentation of a langauge, framework, or tool is the information that describes its functionality. For this part of the practice tasks, you're going to practice digging into documentation and other reference material.

NOTE: The linked documentation for each question below is a good starting place, but you should also be practicing your Googling skills and sifting through the results to find relevant and helpful sites.

2. Data Types (15 min)

Imagine that you're taking your favorite board game and turning it into a computer-based game.

Name of board game: Sorry
Use the space below to categorize game data into each of the following data types. You should have a minimum of two pieces of data for each category.

String data: [Sorry the game of sweet revenge] [For 2-4 players]
Integer and/or float data: players = ['1', '2', '3', '4'] zones = ['1', '2', '3', '4', '5']
Boolean data: If a player is in the safety zone they cannot be bumped: True If a player is not in the safety zone they cannot be bumped: False
Array data: players = ['blue', 'green', 'red', 'yellow] zones = ['Start', 'Slide', 'Safety Zone', 'Home', 'Regular Space']
Hash or Object data: ['Player 1' => 'blue', 'Player 2' => 'green', 'Player 3' => 'red', 'Player 4' => 'yellow']

3. Iteration (30 min)

Create a list below of three real-life situations where iteration is used. For each situation, explain why it would be an example of iteration.
Taking attendance at the beginning of class and marking each student either present or absent
Making a shopping list and write whether you need an item or not if you already have it
A list of chores and marking which items have been completed and what still has to be done
Create a list below of three programming situations where iteration would be used. For each situation, explain why it would be an example of iteration.
You have a list of names and you want them all printed. This is iteration because you are using the print action for all the names listed.
You have a list of clothing item prices and you want to mark them 50% off. You would be making all clothing items 50% off.
You have a list of animals that are extinct and you need to mark them as such. You are adding the same attribute to all of the animals.

4. Modify your Bash Profile (10 min)

Watch this video and follow each step to modify your own bash profile. As mentioned in the video, you will need this snippet below:

# get current branch in git repo
function parse_git_branch() {
  BRANCH=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
  if [ ! "${BRANCH}" == "" ]
  then
    STAT=`parse_git_dirty`
    echo "[${BRANCH}${STAT}]"
  else
    echo ""
  fi
}

# get current status of git repo
function parse_git_dirty {
  status=`git status 2>&1 | tee`
  dirty=`echo -n "${status}" 2> /dev/null | grep "modified:" &> /dev/null; echo "$?"`
  untracked=`echo -n "${status}" 2> /dev/null | grep "Untracked files" &> /dev/null; echo "$?"`
  ahead=`echo -n "${status}" 2> /dev/null | grep "Your branch is ahead of" &> /dev/null; echo "$?"`
  newfile=`echo -n "${status}" 2> /dev/null | grep "new file:" &> /dev/null; echo "$?"`
  renamed=`echo -n "${status}" 2> /dev/null | grep "renamed:" &> /dev/null; echo "$?"`
  deleted=`echo -n "${status}" 2> /dev/null | grep "deleted:" &> /dev/null; echo "$?"`
  bits=''
  if [ "${renamed}" == "0" ]; then
    bits=">${bits}"
  fi
  if [ "${ahead}" == "0" ]; then
    bits="*${bits}"
  fi
  if [ "${newfile}" == "0" ]; then
    bits="+${bits}"
  fi
  if [ "${untracked}" == "0" ]; then
    bits="?${bits}"
  fi
  if [ "${deleted}" == "0" ]; then
    bits="x${bits}"
  fi
  if [ "${dirty}" == "0" ]; then
    bits="!${bits}"
  fi
  if [ ! "${bits}" == "" ]; then
    echo " ${bits}"
  else
    echo ""
  fi
}

export PS1="\u\w\`parse_git_branch\`$ "

5. Questions/Comments/Confusions

If you have any questions, comments, or confusions from the any of the readings that you would an instructor to address, list them below:

I am having trouble with JavaScript Object Values Method

Nice job, @DerekBird! The JavaScript Object.value() method returns the values of an object.

const values = Object.values({ key1: "value1", key2: "value2", key3: "value3 });
// ["value1", "value2", "value3"]
