Annalyn's Infiltration

// @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 again!

//

// A quick reminder about exercise stubs:

//

// 💡 You're allowed to completely clear any 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 ./annalyns-infiltration.spec.js.

//

// 💡 You don't need to write JSDoc comment blocks yourself; it is not expected

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

//

// Now help Annalyn free her best friend!
