JavaScript Assignment #6: Objects

You will complete all of these challenges in the same file.

Start by pasting this object into your code:

const restaurant = {
  name: "Gigi's Pizza Shack",
  address: "123 Main St, Portland OR 97200",
  tags: ["pizza", "family", "dine-in", "take-out", "arcade"],
  website: "http://www.gigispizza.com/",
  staff: {
    owner: {
      name: "Gigi",
      "phone number": "123-234-3456",
    },
    manager: {
      name: "Rose",
      "phone number": "234-345-4567",
    },
    chef: {
      name: "Musa",
      "phone number": "345-456-5678",
    },
  },
}

Challenge #1: Accessing Data

• Use dot or bracket notation as needed to console log the following information:
  • The restaurant's name
  • The third item ("dine-in") from the list of tags
  • The chef's name
• Use a loop to console log each of the tags

Challenge #2: Updating Data

• Using dot or bracket notation to update the object
  • Move the restaurant to somewhere in your city (change the address)
  • Hire yourself to the staff (make up a position for yourself and add it to the "staff")
    • make sure to add yourself as an object with your name and (fake!) phone number
  • Remove the website from the object
• Console log the object to see the changes

Challenge #3: Creating a new object

• Write a new object literal that represents a menu with prices. It can include whatever dishes you like. Give it at least four dishes. An example might look like this:

const menu = {
  burger: 5.0,
  fries: 3.5,
}

Challenge #4: Creating an object method

• Write an order method on the menu object that does the following:
  • takes one argument, an array of strings
  • loop over the strings, and add up the total for the corresponding menu items
  • return the total cost of the order
• For example:
  • console.log(menu.order(["burger", "fries"])) // 8.5
  • console.log(menu.order(["burger", "fries", "fries"])) // 12

Extra challenges (optional)

• Use dot or bracket notation to add the menu to the restaurant object
  • Make an order using restaurant.menu.order()
• Ignore invalid inputs:
  • console.log(menu.order(["burger", "fries", "pasta"])) // 8.5
