As Becky Stern says in the introduction to her latest With Becky Stern video for Digi-Key, "one of the Arduino community's superpowers is code libraries: bundles of specialized programming that allow you to leverage complex computing tools using simple commands." You can use these add-on libraries in your Arduino code to do things like control strips of LEDs, read sensors, and create sounds. There are thousands of user-created libraries out there on the innernets.
In this video, Becky explains more about 'Duino code libraries, shows how to install them, and demonstrates some of the things they can do, in this case, using a strip of NeoPixel LEDs as an example.
