Lab Exercise 01/03/23 - Constructors & Prototypes

In this exercise we explored some of the differences between how classes are defined in Java and JavaScript. Used a car dealership format and created the classes, including their properties and behaviours, using JavaScript.

Created project from scratch and installed dependencies (hint: npm install -D jest).

Task

• Created Car class. The car has properties representing manufacturer, price and engine type.
• Set up Jest and wrote tests to ensure accessibility to each of the properties in a Car object.
• Created a Dealership class. It contains properties representing its name, maximum number of cars it has and the cars currently in stock.
• Added methods to Dealership to:
  • Counted the number of cars in stock
  • Added a car to stock
  • Returned an array containing each car's manufacturer
  • Found all the cars from a given manufacturer
  • Found the total value of all the cars in stock
• Wrote tests for Dealership's methods.
