Libraries Used for this Assignment

• lowdb is a small local JSON database powered by Lodash, which means it has a simple API with functional and chainable methods. lowdb is great for small projects because it doesn't require any setup, and it's file-based, which means that it's easy to work with.

• inquirer is a powerful command line interface tool for Node.js. It provides an easy way to prompt users for input, with various types of questions, such as text input, password input, and multiple choice questions.

• dotenv is a library makes it easy to load environment variables from a .env file in your project and makes them available as properties of the process.env object. This way, you can easily access them in your code and use them to configure your application.
