Overview

Students learn to define and call their own procedures (or “functions”) in order to create and give a name to a group of commands for easy and repeated use in their code. Named procedures are a form of abstraction that enable the programmer to reduce complexity by removing details and generalizing functionality.

Vocab

• Abstraction - a simplified representation of something more complex. Abstractions allow you to hide details to help you manage complexity, focus on relevant concepts, and reason about problems at a higher level.
• Function - A named bit of programming instructions.

New Code

• function myFunction() { // function body, including optional "return" command. }
• Call a function
