// @ts-check

//

// ☝🏽 The line above enables type checking for this file. Various IDEs interpret

// the @ts-check directive. It will give you helpful autocompletion on the web

// and supported IDEs when implementing this exercise. You don't need to

// understand types, JSDoc, or TypeScript in order to complete this JavaScript

// exercise, and can completely ignore this comment block and directive.

​

// πŸ‘‹πŸ½ Hi there!

//

// On the JavaScript track we provide you with stubs. These stubs provide a

// starting point to solving the exercise.

//

// In general, each variable/constant and each declared function will have a

// JSDoc comment block above it, explaining what the variable/constant holds or

// the function is supposed to accomplish.

//

// πŸ’‘ Often, the JSDoc comment blocks have annotations, such as @param and

// @returns which are usually highlighted with a different color if the IDE

// you're in recognizes them. It's these annotations that are used when

// referring to the constant, variable, or function from somewhere else that

// IDEs display.

//

// You don't need to write these yourself; it is not expected in idiomatic

// JavaScript, but some companies and style-guides do enforce them.

//

// πŸ’‘ You're allowed to completely clear a stub before you get started. Often

// we recommend using the stub, because they are already set-up correctly to

// work with the tests, which you can find in ./lasagna.spec.js

//

// Good luck preparing some lasagna!
