Creating Functions

Narrated by Gerilyn, The Coding Copywriter

Functions are groups of commands we give the computer.

Functions help by:

• Making code easier to read
• Abstracting code to work with any value
• Making code easy to reuse
• Dividing a complex problem into simpler ones
• Making code easier to maintain
