Lasagna!
// @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.
// 👋🏽 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.
//
// 💡 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.
//
// 💡 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!
