Dev Advent Calendar 🎅 Puzzle 2 - Elf Coffee Shop 🧝🥤

The Elf Coffee Shop has its big reopening after lengthy renovation works during the summer. Not only is it completely modernized, but has also a whole new range of available drinks. In the old coffee shop, the elves could only choose between "Hot Chocolate" and "Coffee". This new coffee shop has a list of various drinks (e.g. Latte, Hot Chocolate, etc.) and optional flavors (e.g. Gingerbread, Peppermint, etc.).

Since this is new and confusing to the elves, especially because the pricing is a bit more complicated than before, the owner of Elf Coffee Shop asked if you could create an automated menu. He would provide you with the name/price of each drink, and the name/price of each available flavor.

It now is your job to create a list of all possible combinations of these drinks (including those without extra flavor), and the pricing.

🧩 The puzzle

The drinks (drinks) and special flavors (flavors) can be found in the data/drinks.js file and are similar to this:

const drinks = [
    { name: 'Latte', price: 3 },
    { name: 'Hot Chocolate', price: 4.5 },
    ...
]
const flavors = [
    { name: 'Ginerbread', price: 1.5 },
    { name: 'Cinnamon', price: 1 },
    ...
]

Complete the function createMenu in the file utils/menu.js, returning an array of all available drinks including prices (See example result for further aclaration)
Each item in the array should have drink, flavor, and price
price is the total price of drink price + flavor price
Each drink base should also be available as "plain", without extra flavor. This should be represented with flavor: undefined
The menu should be sorted first by drink name, then by price.

Example result

An example result could look like this:

const result = [
    { drink: 'Latte', flavor: undefined, price: 3 },
    { drink: 'Latte', flavor: 'Cinnamon', price: 4 },
    { drink: 'Latte', flavor: 'Peppermint', price: 5 },
    { drink: 'Macchiato', flavor: undefined, price: 10 },
    { drink: 'Macchiato', flavor: 'Cinnamon', price: 11 },
    { drink: 'Macchiato', flavor: 'Peppermint', price: 12 },
]
