This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

JWT means "JSON Web Tokens".

   *   <li>The state of the RateLimiter (storedPermits) is a vertical line in this figure.

* Ask a **question** or ask about a **problem**.
* Suggest a new **feature**.

**Note**: if you do it, then I'm going to ask you to also help others. 😉
