### 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. 

- [ ] In your own words, what does the Ruby array [drop](https://ruby-doc.org/core-2.4.0/Array.html#method-i-drop) method do? As you're explaining, be sure to provide an example. Your answer: The Ruby array drop method removes the first number of specified elements from an array and returns the remaining elements. 
Example 
a = [17, 24, 38, 52, 73, 91] 
a.drop(2) 
[38, 52, 73, 91]

- [ ] What did you Google to help you with this task, and how did you pick your results? 
I initially searched "Ruby array drop method" however this only brought up results from Turing mod 0. I then searched Ruby array method drop and had many more results. 

- [ ] In your own words, what does the Ruby array [push](https://ruby-doc.org/core-2.4.0/Array.html#method-i-push) method do? As you're explaining, be sure to provide an example. Your answer: The Ruby array push method places the specified elements to the end of an array. You may push several elements at the same time. 
Example
a = ["apple", "banana", "peach"]
a.push ("orange", "strawberry")
["apple", "banana", "peach", "orange", "strawberry"]

- [ ] What did you Google to help you with this task, and how did you pick your results? 
I searched "Ruby arrar push method" This time I was given results outside of just Turing materials but it was difficult to determine the date the pages were published or they were older so I searched without quotations.

- [ ] In your own words, what does the Ruby string [split](https://ruby-doc.org/core-2.4.0/String.html#method-i-split) method do? As you're explaining, be sure to provide an example. Your answer: The Ruby arrey split method divides a string into different pieces in a way that the developer defines
Example
"It's raining out".split
["It's", "raining", "out"]

- [ ] What did you Google to help you with this task, and how did you pick your results? 
I searched Ruby string method however the results I got were a bit too technical for me so I searched what does the Ruby string split method do and I was given more results and some in easier to understand terms

- [ ] In your own words, what does the JavaScript array [slice](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice) method do? As you're explaining, be sure to provide an example. Your answer: The JavaScript array slice method selects elements in an array specified by the developer and returns these elements in their own array.
Example
var beers = ['IPA', 'Lager', 'Pilsner', 'Kolsch', 'Stout']
console.log(beers.slice(3));
// expected output: Array ['Kolsch', 'Stout']

- [ ] What did you Google to help you with this task, and how did you pick your results? 
I searched JavaScript array slice method. I began reading an article from W3Schools but remebered I had been warned about using them as a source so I went with an article from StackOverflow instead

- [ ] In your own words, what does the JavaScript object [values](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/values) method do? As you're explaining, be sure to provide an example. Your answer: 

- [ ] What did you Google to help you with this task, and how did you pick your results? 


### 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. 

1. String data: [Sorry the game of sweet revenge]
[For 2-4 players]
1. Integer and/or float data: players = ['1', '2', '3', '4']
zones = ['1', '2', '3', '4', '5']
1. 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
1. Array data: players = ['blue', 'green', 'red', 'yellow]
zones = ['Start', 'Slide', 'Safety Zone', 'Home', 'Regular Space']
1. 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](https://drive.google.com/file/d/1s_CDBnxHSA0HDWldjosulthAvBi-C-d5/view?usp=sharing) 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\`$ "
```
