Functions are code blocks. They do one task.

Why use functions?

• Reuse your code.
• Organize your work.
• Read your code faster.

How to build one:

• Use the function keyword.
• Give it a name.
• Put your code in curly brackets.

Functions run when you call them. Use the same function many times.

Variables inside a function are local. Only the function sees them. You use the same variable name in different functions.

Store function results in variables.

How data moves:

• Parameters: Send values to the function.
• Arguments: The function receives values.
• Code: The function does work.
• Return: The function gives a value back.
