phase-2-challenge-c

Retake of LG Phase-2-Challenge

Phase 2 Interview Challenge

This is the challenge for getting into phase 2.

To get started, create a new repository called phase-2-challenge-c. Do all of your work in this repo and submit it as your solution.

Skills covered:

Programming
Programming in JS
Testing
Node.js
HTML & CSS
Terminal, Bash, & UNIX

Each requirement has a point value. A fully complete requirement gets full points; partially complete requirements get partial points; incomplete requirements get no points. Completeness is determined by calculating points earned divided by total points available.

General Requirements

10: Solution is in a public GitHub repository called phase-2-challenge-c.
10: Solution repository has 4 folders: part-1, part-2, and part-3, and part-4.
20: Git history shows frequent commits.

Part 1: Write tests and solutions for these functions

For the following exercises, write your functions in a file called part-1/functions.js and your tests in a file called part-1/tests.js.

You can use whichever testing tools you prefer: console.assert() (builtin to Node), Mocha and Chai, Jasmine, etc.

Show the day of the week

Write a function weekday(date) to find the day of the week for a given Date object, returing the weekday as a string ('Sunday', 'Monday', 'Tuesday', etc.).

Example:

let dateA = new Date(2017, 5, 15) // June 15, 2017
weekday(dateA) // returns "Thursday"

let dateB = new Date(2017, 11, 31) // Dec 31, 2017
weekday(dateB) // returns "Sunday"

Requirements

10: A test using expected/valid inputs for the weekday() function is written in tests.js.
10: A test using unexpected/invalid inputs for the weekday() function is written in tests.js.
30: Correct implementation of the weekday() is defined in functions.js.
10: Tests for weekday() are passing.

Capitalize every 4th character

Write a function capitalizeFourth(string) that takes a string of words and returns the same string with every 4th character converted to upper case and the rest converted to lower case. Treat whitespace and punctuation characters the same as any other word character.

Example:

capitalizeFourth("Eenie, Meenie, Miney, Moe") // => "eenIe, MeenIe, MineY, mOe"
capitalizeFourth("ABRACADABRA") // => "abrAcadAbra"

Requirements

10: A test using expected/valid inputs for the capitalizeFourth() function is written in tests.js.
10: A test using unexpected/invalid inputs for the capitalizeFourth() function is written in tests.js.
30: Correct implementation of the capitalizeFourth() is defined in functions.js.
10: Tests for capitalizeFourth() are passing.

List of values for object

Write a function getValues(obj) that returns all the values for an object (i.e. the values for each of its properties). Ignore symbolic properties and count only the "own properties" (not inherited) of the object.

Example:

let person = {
  name: 'Dominique',
  age: 30,
  phone: '555-555-5555'
}

getValues(person) // => ['Dominique', 30, '555-555-5555']
getValues({ ids: [4, 8, 2], success: true }) // => [ [4, 8, 2], true ]
getValues({}) // => []

Requirements

10: A test using expected/valid inputs for the getValues() function is written in tests.js.
10: A test using unexpected/invalid inputs for the getValues() function is written in tests.js.
30: Correct implementation of the getValues() is defined in functions.js.
10: Tests for getValues() are passing.

Filter around

Write a function filterAround(array, lower, upper) that takes an array of strings, a lower value, and a upper value. It returns a new array containing only the elements from the source array that come before lower alphabetically and after upper. The elements in the returned array should be in the same order as the source array.

Example:

let animals = ['dog', 'cat', 'zebra', 'ape', 'lion', 'cow']

filterAround(animals, 'cow', 'dog') // => ['cat', 'zebra', 'ape', 'lion']
filterAround(animals, 'chimp', 'lobster') // => ['cat', 'zebra', 'ape']
filterAround(animals, 'aardvark', 'zebu') // => []

Requirements

10: A test using expected/valid inputs for the filterAround() function is written in tests.js.
10: A test using unexpected/invalid inputs for the filterAround() function is written in tests.js.
30: Correct implementation of the filterAround() is defined in functions.js.
10: Tests for filterAround() are passing.

Part 2: Extract data from JSON file

Write a Node.js script to search for data from a JSON file.

Use the cars.json file provided representing a database of cars in a used car lot. Download the file to your part-2/ folder.

Then write two scripts that can be run using the node command.

searchInYears.js takes one argument (let's call it yearRange), finds all the cars from cars.json which have a year that is within the yearRange, and prints the id, make, model, and year of each matching car. The year range format should follow the format YYYY-YYYY, e.g. 1995-2001.
searchByModel.js takes one argument (let's call it the model), finds all the cars from cars.json who have a model value that exactly matches the model argument, and prints the id, model, year, last_owner, and date_purchased of each matching car.

Your searches should not be case-sensitive: i.e. a search for "sorento" is the same as a search for "Sorento".

Example: searchInYears.js

$ node searchInYears.js 1999-2000
Finding cars from 1999 to 2000...

[ { id: 21, make: 'Toyota', model: 'Land Cruiser', year: 1999 },
  { id: 23, make: 'Ford', model: 'Mustang', year: 1999 },
  { id: 26, make: 'Chevrolet', model: 'Metro', year: 2000 },
  { id: 62, make: 'Chrysler', model: 'Sebring', year: 2000 },
  { id: 79, make: 'Chevrolet', model: 'Impala', year: 2000 },
  { id: 85, make: 'Dodge', model: 'Grand Caravan', year: 1999 },
  { id: 92, make: 'Nissan', model: 'Quest', year: 1999 } ]

Example: searchByModel.js

$ node searchByModel.js jetta
Finding cars with model "jetta"...

[ { id: 1,
    model: 'Jetta',
    year: 2011,
    last_owner: 'Kaylil Minico',
    date_purchased: '7/3/2016' },
  { id: 32,
    model: 'Jetta',
    year: 1995,
    last_owner: 'Katerine McEllen',
    date_purchased: '1/8/2004' } ]

Requirements

40: searchInYears.js script prints the car id, make, model, and year for all cars with a year inside the year range provided in the script argument. The range is inclusive—i.e. include cars with the same year as the start year or the end year of the range, as well as all years in between.
40: searchByModel.js script prints the car id, model, year, last_owner, and date_purchased for all cars with a model that matches the provided argument (ignoring case).

Part 3: HTML layout for Bookstore

Write the HTML & CSS to layout a page for an online bookstore.

You only need to write HTML & CSS. No JavaScript or web server is required.

Design a layout to match the following wireframe:

Part 4: Quiz time!

Copy the questions below into a file part-4/quiz.md. Then, write your answer to each question directly below it.

The quiz is worth 50 points in total.

Reminder: you can use the internet to help you answer these questions :)

What is the PATH environment variable used for in UNIX systems?
On a UNIX computer, how do you stop a running process?
Which command can you use to see which homebrew packages you've installed?
On a UNIX computer, how do you find the process id of a running process?
In a terminal, what does control-c do?

What would be the result of typing the following commands?

$ cd /Users/lucy
$ mkdir one
$ touch alpha
$ cd one
$ touch alpha
$ pwd

How do you see which environment variables are set in your shell?
What keyboard shortcut do you use to perform a "Find" search in your editor?
How do you see which aliases you have in your shell?
When a terminal command completes, how can you tell if it was successful or not?
What does your ~/.gitconfig have in it? (paste the whole file here)
What is the difference between a relative and absolute path?

Lets say you have the following file structure

~
└── Projects
    ├── airbnb-for-llamas
    │   └── package.json
    └── facebook-for-mimes
        ├── README.md
        └── package.json

And you were in the facebook-for-mimes folder. What command would you use to copy the README.md file to the airbnb-for-llamas folder?

What keyboard shortcut do you use in your editor to quickly navigate to a file in the current project?
Give an example of a file or folder pattern you commonly add to a .gitignore file and why you add it
