Advanced Test - Programming Basics

Task 1 - Key Value Pairs

Create an object called profileData that represents a user
The object should have 4 keys: firstName, lastName, age and city
Use values of your choice for each key

Task 2 - Object method

Add a new property to the profileData object called details. This property is a method that returns a string describing the user like in the example below:
```
console.log(profileData.details());
```
Expected Output:
```
Jess Smith is 30 years old and lives in Berlin
```

Task 3 - Word Converter

Create a function called wordConverter
The function has two parameters:
- words: an array of words
- suffix: a string
Inside the function, use an array method to add the suffix to the end of all the words in the array
Important: Do not use a a for loop and forEach to complete this task

Look at the expected output below.

Example

let adjectives = ["smart", "kind", "sweet", "small", "clear"];

Call your function and print the returned value to the console.

Expected output

> console.log(wordConverter(adjectives, "er"));
[ 'smarter', 'kinder', 'sweeter', 'smaller', 'clearer' ]

Task 4 - Hour Calculation

Create a function called calculateHours
the function has one parameter:
- hours: an array of objects containing a day, start and end hour, describing the working hours of a single person (see example below)
the function calculates and returns how many hours (total) this person worked in the week based on the items in the given array

Note: Assume that start is always morning time, end is always afternoon. (No overnight shifts to be expected)

Example array of Working Hours

const hourTracking = [
    { day: 'Monday', start: 8, end: 17},
    { day: 'Tuesday', start: 9, end: 15},
    { day: 'Wednesday', start: 10, end: 18},
    { day: 'Thursday', start: 7, end: 14},
    { day: 'Friday', start: 6, end: 12},
];

Call your function and print the return value to the console.

Expected Output

> console.log(calculateHours(hourTracking));
36

Task 5 - Classes

Create a class called Course to represent a course at DCI
Add a constructor to initialize the properties in the given order.
Class properties:
- teacher: a string with the name of the teacher
- type: a string to specify the type of the course. For example, "web development"
- number: a number to specify how many students are taking the course
Class methods:
- spaceNeeded(): calculates and returns a number how big a classroom should be depending on the number of students taking the course and returns that value. Assume that for each student 2m² are necessary.
  - For example:
    - for a class of 10 students the return value would be 20
    - for a class of 25 students, the return value would be 50
- details(): returns a string describing the course, for example: "This is a web development course taught by John Smith. There are 10 students taking the course."
  - fill in the teacher, type and number from your class properties.
Create an instance of your class, and test the different methods printing their result to the console

Example: for an instance with teacher John, type web development and a number of 22 students
```
> console.log(course.spaceNeeded());
44

> console.log(course.details());
This is a web development course taught by John. There are 22 students taking the course.
```

Task 6 - Input validation

A PIN is a Personal Identification Number (as you are used with bank cards and unlocking your mobile phone)
Create the function validPin
The function should return true or false if the PIN satisfies all the requirements below or not:

Requirements:
- The pin code must consist of only numerical digits
- The pin code must be 4 digits long
- The pin code's last digit should be even (0, 2, 4, 6, 8)
- The first digit of the pin code should be different from the last one
The function should return:
- true: if the PIN code satisfies all the requirements
- false: if even a single requirement is not satisfied

Call your function with some examples, and print the return values to the console

Examples

> console.log(validPin("1234"));
true
> console.log(validPin("1235"));// last number should be even
false 
> console.log(validPin("12ww"));// should only consist of numbers
false 
> console.log(validPin("12.4"));// should only consist of numbers
false
> console.log(validPin("-234"));// should only consist of numbers
false
> console.log(validPin("12345"));// should be 4 digits, not 5
false 
> console.log(validPin("2222"));// first and last digits should be different
false 
> console.log(validPin("2224"));
true
