Packages can be thought of plug-ins for your code. Sometimes called libraries or modules, packages offer a defined set of functionality you can import into your application. You will find it's almost impossible to create an application which doesn't use multiple packages.

By using npm (Node Package Manager) you can access an entire world of tools and resources. If you are trying to implement common services like creating a web application, managing secrets, calling external resources, or incorporating artificial intelligence, chances are there's a package available to suit your needs.
