Tasks 📃

• 0. Rectangle #0

  • 0-rectangle.js: JavaScript script that defines an empty class Rectangle.

• 1. Rectangle #1

  • 1-rectangle.js: JavaScript script that defines a class Rectangle. Builds on 0-rectangle.js with:
    • Constructor that initializes instance attributes width and height with given parameters w and h.

• 2. Rectangle #2

  • 2-rectangle.js: JavaScript script that defines a class Rectangle. Builds on 1-rectangle.js with:
    • If provided w and h are less than or equal to 0, creates an empty object.

• 3. Rectangle #3

  • 3-rectangle.js: JavaScript script that defines a class Rectangle. Builds on 3-rectangle.js with:
    • Instance method print() that prints the rectangle using the X character.

• 4. Rectangle #4

  • 4-rectangle.js: JavaScript script that defines a class Rectangle. Builds on 4-rectangle.js with:
    • Instance method rotate() that swaps the width and height of the Rectangle.
    • Instance method double() that multiplies the width and height of the Rectangle by 2.

• 5. Square #0

  • 5-square.js: JavaScript script that defines a class Square that inherits from Rectangle.
    • Constructor takes one argument size.

• 6. Square #1

  • 6-square.js: JavaScript script that defines a class Square that inherits from Rectangle. Builds on 5-square.js with:
    • Instance method charPrint(c) that prints the Square using the character c.
    • If c is undefined, uses the character X.

• 7. Occurrences

  • 7-occurrences.js: JavaScript function that returns the number of occurrences in a list.

• 8. Esrever

  • 8-esrever.js: JavaScript function that reverses a list.

• 9. Log me

  • 9-logme.js: JavaScript function that prints the number of arguments already printed as well as the new argument value.
  • Output: <number arguments already printed>: <current argument value>

• 10. Number conversion

  • 10-converter.js: JavaScript function that converts a number from base 10 to another base passed as argument.

• 11. Factor index

  • 100-map.js: JavaScript script that imports an array and creates a new array with each value equal to the value of initial list times the index of the new list.
  • Prints both the initial and new list.

• 12. Sorted occurences

  • 101-sorted.js: JavaScript script that imports a dictionary of occurrences by user ID and computes a new dictionary of user ID's by occurrences.
  • Prints the new dictionary.

• 13. Concat files

  • 102-concat.js: JavaScript script that concatenates two files passed as arguments into a file specifed as the third argument.
