Now that we've had guidance on setting intent, what would you like the intent for today's class to be?
Discuss as a class, and keep this in mind throughout your day.
- In JavaScript,
.?is the symbol for optional chaining. What is optional chaining, and where/when would you use it? - What is wrong with the following code
const delete = (item) => {
console.log('item was deleted')
}-
a vending machine is an object
-
it has an array of snacks (make 3 snacks)
-
snacks are objects that have a name and a price
-
a vending machine has a function vend that allows the user to enter the array position (a number) of the snack, and then that snack will be returned
-
Be able to call vendingMachine.vend() with a valid integer to return a snack
The goal will be to play a simple game of Blackjack (two players, each gets two cards, determine who wins)
Note: We will continue to work on solving this after the second lesson on OOP, and you will get more time to work on this problem during the next session
-
Cards with a face of 2 - 10, jack, queen, king ace
-
Values of cards 2-10 are the same as the face. Jack, queen, and king are worth 10. Ace starts as a value of 11 but can be changed to a value of 1
-
There are 4 sets of 13 cards (hearts, diamonds, spades, clubs)
-
The card objects should go in an array
-
There should be a method that 'shuffles' the deck. The card objects can be reordered
-
As each play happens, two cards are given to the player, and two are given to the computer player - these cards are removed from the array of card objects
Write down any questions about this model. What information is needed? What other considerations are there?
- Make a simple BlackJack game to be played in the console
Both of these are from the book Cracking the Code Interview. Work with a partner to discuss and design the following:
- Model a Jukebox
- Model a Call Center
