array_of_objects.js

let cart = [
    {
        "name": "apple",
        "price": 1.25,
        "quantity": 5
    },
    {
        "name": "kiwi",
        "price": 3.99,
        "quantity": 7
    },
    {
        "name": "orange",
        "price": 1.50,
        "quantity": 8
    },
]

// How would we determine how many types of items are in the cart? What if there are more than we can reasonably, manually count?

// Write the code necessary to access the number of apples

// Write the code necessary to determine how much we spent on kiwis, in total

// Write the code to sum up the quantity of all items in the cart

// Write the code necessary to update the cost of each fruit to be 30% more.

// Write the code necessary to determine the average cost per item. Add price*quantity for each item together then divide by the total number.

// Write the code necessary to convert each item's price property into a string with a dollar sign like "$1.50"

// Write the code necessary to capitalize the first letter of each item's name property.
